Information contained herein is subject to completion or amendment. A registration statement relating to these securities has been filed with the Securities and Exchange Commission. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective.

PROSPECTUS

Subject to Completion, Dated April 18, 1997

12,101,409 SHARES

DISCOVERY LABORATORIES, INC.

COMMON STOCK

This Prospectus relates to the offer (the "Offering") by the securityholders named herein under the caption "Selling Securityholders" (collectively, the "Selling Securityholders") for sale to the public of the following securities of Discovery Laboratories, Inc. ("Discovery"): (i) 2,200,256 shares of Discovery's common stock, par value $0.001 per share ("Common Stock"); (ii) 8,801,024 shares of Common Stock issuable upon conversion of currently outstanding shares of Series A Convertible Preferred Stock, par value $0.001 per share, of Discovery ("Series A Preferred Stock"); (iii) 220,026 shares of Common Stock issuable upon exercise of certain warrants issued to the placement agent of the Unit Offering described herein (the "Common Placement Warrants") and (iv) 880,103 shares of Common Stock issuable upon the conversion of shares of Series A Preferred Stock issuable upon exercise of certain warrants issued to the placement agent of such Unit Offering (the "Preferred Placement Warrants" and, together with the Common Placement Warrants, the "Placement Agent Warrants"). The number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock is subject to adjustment in certain events.

Discovery will not receive any proceeds from the sale of shares of Common Stock. Discovery is not expected to receive any proceeds from the exercise of the Placement Agent Warrants since the Placement Agent Warrants may be exercised pursuant to cashless exercise provisions. In the event that the Placement Agent Warrants are exercised for cash, Discovery intends to use such net cash proceeds
(after estimated offering expenses of the Offering of approximately $300,000)
for general working capital purposes. Proceeds, if any, from the exercise for cash of all the Placement Agent Warrants, before deduction of estimated expenses of the Offering, would be approximately $2,475,000. Whether and to what extent any of the Placement Agent Warrants will be exercised, and whether the Placement Agent Warrants are exercised for cash or not, cannot be predicted by Discovery.

The Selling Securityholders have advised Discovery that they may sell, directly or through brokers, all or a portion of the securities offered hereby in negotiated transactions or in one or more transactions in the market at the price prevailing at the time of sale. In connection with such sales, the Selling Securityholders and any participating brokers may be deemed to be "underwriters" of the Common Stock within the meaning of the Securities Act of 1933. It is anticipated that usual and customary brokerage fees will be paid by the Selling Securityholders in all open market transactions. Discovery will pay all other expenses of this Offering. See "Plan of Distribution."

Discovery will inform the Selling Securityholders that the anti-manipulation provisions of Regulation M under the Securities Exchange Act of 1934 may apply to the sales of their shares offered hereby. Discovery also will advise the Selling Securityholders of the requirement for delivery of this Prospectus in connection with any sale of the shares offered hereby.

Discovery is in the research and development stage, has not had any operating revenues, and at December 31, 1996, had an accumulated deficit of approximately $3,254,000. Discovery is continuing to incur losses and expects to incur significantly increasing additional losses for the foreseeable future.

Prior to the Offering, there has been no public market for the Common Stock and there can be no assurance that such a market will develop or, if developed, that it will be sustained. Discovery intends to apply for listing of the Common Stock on the National Association of Securities Dealers Automated Quotation Small-Cap Market(R) ("Nasdaq Small-Cap Market") under the symbol "DSCO". The prices of the Common Stock which may be obtained on any such market are not necessarily related to Discovery's assets, book value, results of operations or any other established criteria of value, and should not be regarded as any indication of future market price of the Common Stock. See "Risk Factors," "Description of Securities" and "Plan of Distribution."

THE SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK.
SEE "RISK FACTORS", P. 5.

THE COMMON STOCK HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND

EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION

TO THE CONTRARY IS A CRIMINAL OFFENSE.

THE DATE OF THIS PROSPECTUS IS ____, 1997

PROSPECTUS SUMMARY

THE FOLLOWING SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MORE DETAILED INFORMATION AND THE FINANCIAL STATEMENTS AND NOTES THERETO, INCLUDING, WITHOUT LIMITATION, THE INFORMATION UNDER "RISK FACTORS," APPEARING ELSEWHERE IN THIS PROSPECTUS OR INCORPORATED HEREIN BY REFERENCE, AND, ACCORDINGLY, SHOULD BE READ IN CONJUNCTION THEREWITH. REFERENCES IN THIS PROSPECTUS TO "DISCOVERY" REFER TO DISCOVERY LABORATORIES, INC., AND REFERENCES TO THE "COMPANY" REFER TO DISCOVERY LABORATORIES, INC. AND ITS MAJORITY-OWNED SUBSIDIARY, ACUTE THERAPEUTICS, INC. ("ATI"), UNLESS THE CONTEXT OTHERWISE REQUIRES.

COMPANY SUMMARY

The Company is a development stage pharmaceutical company that is focused on acquiring, developing and commercializing proprietary investigational drugs that have previously been tested in humans or animals. The Company's strategy is to conduct preclinical and clinical studies on investigational drugs licensed from third parties, either on its own or in collaboration with corporate partners. The Company may also seek to enter into collaborations with corporate partners for manufacturing and marketing of such drugs. The Company currently has three licensed investigational drug candidates under development.

SUPERVENT(TM)

The Company is developing SuperVent(TM) as a stable aerosolized, multidimensional therapy for airway diseases characterized by inflammation, injurious oxidation and excessive sputum. SuperVent's(TM) active compound is tyloxapol, a compound which has been safely used as an emulsifying agent in drug formulations by the pharmaceutical industry for over 40 years. Experimental research has led to the discovery that tyloxapol appears to possess biological activities beyond its well-recognized emulsification properties. In March 1996, the Company obtained an exclusive, worldwide license from The Charlotte-Mecklenburg Hospital Authority ("CMHA") which covers two issued United States patents, three pending United States patent applications, and corresponding foreign patent applications, relating to pharmaceutical preparations containing high concentrations of tyloxapol and to the use of tyloxapol for the treatment of a variety of respiratory and other diseases involving inflammation and oxidative damage. The United States Food and Drug Administration (the "FDA") has granted orphan drug status for the use of tyloxapol to treat cystic fibrosis ("CF").

The Company intends to clinically test SuperVent(TM) for the treatment of CF and chronic bronchitis. CF is a progressive respiratory disease that afflicts approximately 23,000 patients in the United States and a comparable number of patients in Europe. It is the most common lethal genetic disease among Caucasians. The FDA, subject to certain modifications, has approved a physician-sponsored Investigational New Drug ("IND") application for a proposed randomized, double-blinded, placebo-controlled Phase I/II clinical trial of SuperVent(TM) for the treatment of CF. The Company entered into a clinical research agreement with the University of Utah Health Sciences Center ("UHSC") and began the aforementioned trial on March 17, 1997, pursuant to such agreement. Assuming the successful completion of the trial, the Company intends to commence a multi-center, Phase III clinical trial in CF and to file an additional IND to commence a Phase II clinical trial for the treatment of chronic bronchitis. Chronic bronchitis is a disease characterized by inflammation of the airways leading to coughing and excessive mucus production. There are an estimated 14,000,000 chronic bronchitis patients in the United States, many of whom are habitual smokers. If successfully developed and approved, SuperVent(TM) is intended to be used daily by CF and chronic bronchitis patients in the home or hospital to preserve pulmonary function and aid mucus expectoration.

KL4-SURFACTANT

KL4-Surfactant is a proprietary, synthetic lung surfactant invented at The Scripps Research Institute ("Scripps"). The product was exclusively licensed to Johnson & Johnson, Inc. ("J&J"), which completed a multi-center, Phase II clinical trial of KL4-Surfactant for the treatment of infant respiratory distress syndrome ("IRDS"). The Phase II trial demonstrated safety and efficacy comparable to that of the bovine-derived surfactant, Survanta(TM), marketed by Ross Laboratories. In

1

October 1996, Discovery's majority-owned subsidiary, ATI, acquired the exclusive worldwide sublicense to the KL4- Surfactant technology.

The Company is currently developing KL4-Surfactant for the treatment of meconium aspiration syndrome ("MAS") and adult respiratory distress syndrome ("ARDS"). The Company may also develop KL4-Surfactant for IRDS. MAS is a disease affecting approximately 26,000 newborn babies per year in the United States that results from the release of fetal bowel contents into the amniotic fluid and its subsequent aspiration into the fetal lung. ARDS is a generalized inflammatory disease of the lungs marked by intense leukocytic infiltration, edema and atelectasis (partial lung collapse) resulting from sepsis, smoke inhalation and other inflammatory lung conditions. IRDS is a disease of pre-term infants who are born prior to the synthesis of adequate amounts of pulmonary surfactant proteins. ATI intends to seek FDA approval to amend an approved IND and to initiate Phase II clinical trials of KL4-Surfactant for the treatment of ARDS in 1997. ATI has amended an existing IRDS IND to permit the initiation of Phase II clinical trials for the use of KL4-Surfactant to treat MAS. ATI met with the FDA on March 10, 1997, to discuss its MAS development program. ATI received constructive feedback from the FDA and intends to commence its MAS development program on schedule.

ST-630

In October 1996, the Company acquired an exclusive license from the Wisconsin Alumni Research Foundation ("WARF") relating to an active vitamin D analog, ST-630, and its potential use in treating postmenopausal osteoporosis. Osteoporosis is a disease characterized by decreased bone mass that leads to reduced bone strength and an increased risk of fractures. Postmenopausal osteoporosis is a major public health threat for approximately 7 to 20 million American women. As a class, vitamin D analogs are commonly used therapies in Europe and Japan for osteoporosis. Sumitomo Pharmaceuticals ("Sumitomo") and Taisho Pharmaceuticals ("Taisho") have jointly licensed the right to develop, manufacture and market ST-630 in Japan for the treatment of osteoporosis and are presently conducting the equivalent of a Phase II clinical trial in Japan. The Company believes that ST-630 may have an improved pharmacological profile compared to earlier active vitamin D analogs. As a result of the execution of the WARF license agreement, the Company has access to preclinical data generated by Sumitomo and Taisho. The Company intends to seek FDA permission to initiate clinical studies of ST-630 in the United States as a once-daily, orally administered drug for the treatment of postmenopausal osteoporosis.

The Company was incorporated in Delaware on May 18, 1993, as MicroBio, Inc. and subsequently changed its name to Discovery Laboratories, Inc. on May 23, 1996. The Company did not commence its current operations until early 1996. The Company's executive offices are located at 787 Seventh Avenue, 44th Floor, New York, New York 10019. Its telephone number is (212) 554-4364 and its facsimile number is (212) 554-4490. ATI was incorporated on September 11, 1996. Its principal offices are located at 3359 Durham Road, Doylestown, PA, 18901. Its telephone number is (215) 794-3064 and its facsimile number is (215) 794-3239.

SUPERVENT(TM) IS A TRADEMARK OF THE COMPANY. SURVANTA(TM) IS A TRADEMARK OF ROSS LABORATORIES, INC. THIS PROSPECTUS INCLUDES PRODUCT NAMES, TRADEMARKS AND TRADE NAMES OF COMPANIES OTHER THAN THOSE OF THE COMPANY.

                                       Warrants since the Placement Agent Warrants may be exercised pursuant to a cashless
                                       exercise provision.  In the event that the Placement Agent Warrants are exercised for cash,
                                       the Company intends to use such net cash proceeds (after estimated offering expenses of

                                       of estimated expenses of this Offering, would be approximately $2,475,000.  Whether, how

RISK FACTORS

AN INVESTMENT IN THE SECURITIES OFFERED HEREBY IS HIGHLY SPECULATIVE IN NATURE, INVOLVES A HIGH DEGREE OF RISK AND SHOULD ONLY BE MADE BY AN INVESTOR WHO CAN BEAR THE ECONOMIC RISK OF THE INVESTMENT FOR AN INDEFINITE PERIOD OF TIME AND WHO CAN AFFORD A LOSS OF THE ENTIRE INVESTMENT. EACH PROSPECTIVE INVESTOR SHOULD CAREFULLY CONSIDER THE RISKS ASSOCIATED WITH AN INVESTMENT IN THE COMPANY, INCLUDING, WITHOUT LIMITATION, THE FOLLOWING RISK FACTORS, AS WELL AS OTHER INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS BEFORE MAKING AN INVESTMENT.

DEVELOPMENT STAGE COMPANY; NO DEVELOPED OR APPROVED PRODUCTS; UNCERTAINTY OF FUTURE PROFITABILITY

The Company is at an early stage of development and has had almost no operations to date. The potential products upon which the Company intends to focus its development efforts are in the research and development stage and accordingly the Company has not begun to market or generate revenues from the commercialization of any of these products under development. The Company's products under development will require significant time-consuming and costly research, development, preclinical studies, clinical testing, regulatory approval and significant additional investment prior to their commercialization, which may never occur. Such clinical testing activities, together with resultant increases in general and administrative expenses, are expected to result in significant additional operating losses for the foreseeable future. The Company currently is not profitable and does not anticipate generating significant product revenues for the foreseeable future, if at all. The Company expects to incur significant increasing operating losses over the next several years. To achieve profitable operations, the Company, alone or with others, must successfully develop and obtain regulatory approval for marketing its products.

The Company's operations are subject to numerous risks associated with the establishment and development of products based upon innovative or novel technologies. As a result, the Company must be evaluated in light of the problems, delays, uncertainties and complications encountered in connection with newly founded businesses. Some of these unanticipated problems may include development, regulatory, manufacturing, distribution and marketing difficulties that may be beyond the Company's financial or technical abilities to satisfactorily resolve. In particular, there can be no assurance that the Company's proposed drug products will not cause adverse effects that may prevent them from being marketed, regardless of their efficacy. Certain of the Company's initial drug candidates have not been the subject of Phase I clinical trials, the purpose of which include identifying adverse effects, or have not been the subject of such clinical trials at the dosage levels at which the Company anticipates they will be administered in treating the indications for which the Company is exploring their use. Moreover, those that have been the subject of previous clinical trials may be shown to have previously undetected adverse effects during the more extensive clinical trials that will be required prior to their becoming candidates for marketing approval by the FDA. There can be no assurance that the research and development activities funded by the Company will be successful, that products under development will prove to be safe and effective, that any of the preclinical or clinical development work will be completed, that the Company will ever achieve any of its New Drug Application ("NDA") filing objectives with the FDA, that FDA approval will be attained for such products, that the anticipated products will be commercially viable or successfully marketed, that third parties do not hold proprietary rights that preclude the Company from marketing its products, if any, or that, if the products under development are approved by the FDA, the Company will ever achieve significant revenues or profitable operations. See "Business."

EXTENSIVE GOVERNMENT REGULATION; UNCERTAINTY OF FDA AND OTHER GOVERNMENTAL APPROVAL OF PRODUCTS UNDER DEVELOPMENT

The testing, manufacture, distribution, advertising and marketing of drug products are subject to extensive regulation by governmental authorities in the United States and other countries. Prior to marketing, any pharmaceutical products developed or licensed by the Company must undergo an extensive regulatory approval process required by the FDA and by comparable agencies in other countries. This process, which includes preclinical studies and clinical trials of each pharmaceutical compound to establish its safety and effectiveness and confirmation by the FDA that good laboratory, clinical and manufacturing practices were maintained during testing and manufacturing, can take many years, requires the expenditure of substantial resources and gives larger companies with greater financial resources a competitive advantage

5

over the Company. The FDA review process can be lengthy and unpredictable, and the Company may encounter delays or rejections of its applications when submitted. If questions arise during the FDA review process, approval may take a significantly longer period of time. Generally, in order to gain FDA approval, a company must conduct preclinical studies in a laboratory and in animal models to obtain preliminary information on a compound's efficacy and to identify any safety problems. The results of these studies are submitted as part of an IND application that the FDA must review before human clinical trials of an investigational drug can start. Clinical trials are normally done in three phases and generally take two to five years or longer to complete.

The regulatory status of the Company's three products under development is as follows:

SuperVent(TM):

The FDA has approved, subject to certain modifications, a physician- sponsored IND for a randomized, double-blinded, placebo-controlled Phase I/II clinical trial of the Company's drug candidate, SuperVent(TM), for the treatment of CF. The Company entered into a clinical research agreement with the University of Utah Health Sciences Center ("UHSC") and began the aforementioned trial on March 17, 1997, pursuant to such agreement. Assuming successful completion of the Phase I/II clinical trial of SuperVent(TM), the Company anticipates that, at a minimum, at least one additional large-scale, multi-center, Phase III clinical trial will be necessary before the Company will be able to submit an NDA to the FDA requesting marketing approval for SuperVent(TM) for the treatment of CF.

KL4-Surfactant:

In July 1992, an IND submitted by Scripps relating to the use of KL4-Surfactant to treat IRDS was approved by the FDA. A Phase II clinical trial was subsequently completed by J&J. In 1991, an IND was submitted by J&J relating to the use of KL4-Surfactant to treat ARDS and was subsequently approved by the FDA. Both the IRDS IND and ARDS IND have been transferred to ATI. ATI intends to seek FDA approval to amend the approved ARDS IND and re-initiate Phase II clinical trials of KL4-Surfactant for the treatment of ARDS in 1997. ATI has amended the existing IRDS IND to permit the initiation of Phase II clinical trials of KL4-Surfactant to treat MAS. ATI met with the FDA on March 10, 1997, to discuss its MAS development program. ATI received constructive feedback from the FDA and intends to commence its development of KL4-Surfactant for MAS on schedule. The Company has not had any discussions with the FDA regarding clinical trials of KL4-Surfactant for the treatment of ARDS.

ST-630:

The Company intends to seek IND approval to initiate Phase I clinical studies of ST-630 as a once-daily, orally administered drug for the treatment of postmenopausal osteoporosis in the United States during 1997. Following receipt of FDA approval, if granted, the Company intends to conduct an initial dose-ranging study of ST-630 in humans. Based upon the results of the dose-ranging study, the Company may then either seek to further optimize the delivery of ST-630 by testing one or more alternative means of delivery or, assuming acceptable results, seek to initiate a large-scale, multi-center clinical trial in the United States. The Company has access to preclinical data generated by Sumitomo and Taisho with respect to ST-630 pursuant to the terms of the licensing arrangements described herein with respect to ST-630. The Company has not had any discussions with the FDA regarding ST-630. See "Business--Products and Technologies Under Development--Vitamin D Analog for Treatment of Osteoporosis--ST-630."

Upon completion of clinical trials of a new drug product, FDA and foreign regulatory authority marketing approval must be obtained before the new drug product can be sold. NDAs submitted to the FDA generally take one to three years to be approved. If questions arise during the FDA review process, approval may take a significantly longer period of time. The testing and approval processes require substantial time and effort and there can be no assurance that any

6

approval will be granted on a timely basis, if at all. Even if regulatory clearances are obtained, a marketed product is subject to continual review, and later discovery of previously unknown problems or failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. For marketing outside the United States, the Company also will be subject to foreign regulatory requirements governing human clinical trials and marketing approval for pharmaceutical products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. None of the Company's products under development have been approved for marketing in the United States or elsewhere (nor has testing been completed). No assurance can be given that the Company will be able to obtain regulatory approval for any such products under development. Failure to obtain requisite governmental approvals or failure to obtain approvals of the scope requested will delay or preclude the Company or its licensees or marketing partners from marketing the Company's products under development, or limit the commercial use of such products, and thereby could have a material adverse effect on the Company's business, financial condition and results of operations.

TECHNOLOGICAL UNCERTAINTY AND OBSOLESCENCE

The market for biotechnology is characterized by rapidly changing technology and evolving industry standards. The Company's future success will depend upon its ability to develop and commercialize its existing products and to develop new products and applications. There can be no assurance that the Company will successfully complete the development of SuperVent(TM), KL4-Surfactant, ST-630 or any future product or that the Company's current or future products will achieve market acceptance. Any delay or failure of SuperVent(TM), KL4-Surfactant, ST-630 or any future product which the Company may develop in achieving market acceptance would adversely affect the Company's business.

The Company's products under development are intended to treat diseases for which other technologies and proposed treatments are rapidly developing. There can be no assurance that any results of the Company's research and product development efforts will not be rendered obsolete by research efforts and technological activities of others, including the efforts and activities of governments, major research facilities and large multinational corporations.

NEED FOR ADDITIONAL FINANCING; ISSUANCE OF SECURITIES; FUTURE DILUTION

In the future, the Company will require substantial additional funding to conduct its research and product development activities and to manufacture and market, if approved by the FDA or corresponding foreign regulatory authorities, SuperVent(TM), KL4-Surfactant, ST-630 and any other products that the Company may develop in the future. The Company anticipates that further funds may be raised through collaborative ventures entered into with potential corporate partners and/or additional debt or equity financings. While the Company may seek to enter into collaborative ventures with corporate sponsors to fund some or all of its research and development activities, as well as to manufacture or market any products which may be successfully developed, the Company currently does not have any such arrangements with corporate sponsors. The Company also has not made arrangements to obtain any additional financing and there can be no assurance that the Company will be able to obtain adequate additional financing on acceptable terms, if at all, or that any such additional financing would not result in significant dilution of stockholders' interests. Failure by the Company to enter into collaborative ventures or to receive additional funding to complete its proposed product development programs would have a material adverse effect on the Company. If additional financing is not otherwise available, the Company will be required to modify its business development plans or reduce or cease certain or all of its operations.

DEPENDENCE ON PATENTS, LICENSES AND PROTECTION OF PROPRIETARY RIGHTS; RISK OF LOSS OF TECHNOLOGY

In order to justify the substantial investment of time and expense required to develop and commercialize its products, the Company will seek proprietary protection for its drug candidates so as to prevent others from commercializing equivalent products in substantially less time and at substantially lower expense. The pharmaceutical industry places considerable importance on obtaining patent and trade secret protection for new technologies, products and processes. The Company's success will depend in part on the ability of the Company and the Company's licensors to obtain effective patent protection for the Company's proprietary technologies and products, defend such patents, preserve its trade secrets and operate without infringing upon the proprietary rights of others, both in the United States and in other countries. The patent position of firms relying upon biotechnologies is highly uncertain and involves complex legal and factual questions.

7

To date, there has emerged no consistent policy at the United States Patent and Trademark Office regarding the breadth of claims allowed in biotechnology patents or the degree of protection afforded under such patents.

There are various combinations of United States and foreign patents and patent applications (including international applications filed under the Patent Cooperation Treaty) that have been issued or filed with respect to the products and technologies under development by the Company. See "Business--Licensing Arrangements." These patents and patent applications have been licensed to the Company (with certain limited exceptions, on an exclusive worldwide basis). Although the licensors under such licenses have retained control of the patent prosecution process, the Company is responsible for the expenses of prosecuting the patents and patent applications (i.e., the fees of patent counsel and any domestic or foreign filing fees that are applicable). Patent applications may be expected to remain pending for several years before the issuance of a patent, if any, and the prosecution of patent applications with respect to the Company's products may entail considerable expense to the Company.

There can be no assurance that patents will issue as a result of any of the pending patent applications relating to the Company's products and technologies or that the issued patents and any patents resulting from the pending patent applications will be sufficiently broad to afford protection to the Company against competitors with similar products and technologies. In addition, there can be no assurance that such patents will not be challenged, invalidated or circumvented, or that the rights granted thereunder will provide competitive advantages to the Company. The commercial success of the Company will also depend upon its avoidance of infringement of patents issued to competitors. A United States patent application is maintained under conditions of confidentiality while the application is pending, so the Company cannot determine the inventions being claimed in pending patent applications filed by third parties. Litigation may be necessary to defend or enforce the Company's patent and license rights or to determine the scope and validity of the proprietary rights of others. Defense and enforcement of patent claims can be expensive and time-consuming, even in those instances in which the outcome is favorable to the Company, and can result in the diversion of substantial resources from the Company's other activities. An adverse outcome could subject the Company to significant liabilities to third parties, require the Company to obtain licenses from third parties, or require the Company to alter its products or processes or cease altogether any related research and development activities or product sales, any of which could have a material adverse effect on the Company's business, financial condition and results of operations. See "Business--Patents, Licenses and Proprietary Rights."

The Company requires all employees to enter into confidentiality agreements that prohibit the disclosure of confidential information to third parties and require disclosure and assignment to the Company of rights to such employees' ideas, developments, discoveries and inventions. In addition, the Company seeks to obtain such agreements from its consultants, advisors and research collaborators. To the extent that consultants, key employees or other third parties apply technological information independently developed by them or by others to any of the proposed projects of the Company, disputes may arise as to the proprietary rights to such information which may not be resolved in favor of the Company. In addition, the Company also relies on trade secrets and proprietary know-how that it seeks to protect in part by its confidentiality agreements with its employees, consultants, advisors or others. There can be no assurance that these agreements will not be breached, that the Company would obtain adequate remedies for any breach, or that the Company's trade secrets or proprietary know-how will not otherwise become known or be independently developed by competitors in such a manner that the Company has no legal recourse. See "Business--Patents, Licenses and Proprietary Rights."

The Company is dependent on licensing arrangements for access to its products under development, and the Company is required to make certain payments and satisfy certain performance obligations in order to maintain the effectiveness of such licensing arrangements. The Company is further responsible for the cost of filing and prosecuting patent applications and maintaining issued patents. See "Business--Patents, Licenses and Proprietary Rights." If the Company does not meet its due diligence and/or financial obligations under its license agreements in a timely manner, the Company could lose the rights to its proprietary technology, which would have a material adverse effect on the Company.

DEPENDENCE ON THIRD PARTY SUPPLIERS; LACK OF MANUFACTURING CAPABILITY

The Company does not have any manufacturing capacity of its own but instead intends to rely on outside manufacturers to produce appropriate clinical grade material for its use in clinical studies for certain of its products. To be successful, the Company's products must be manufactured in commercial quantities under good manufacturing practice ("GMP") requirements presented by the FDA at acceptable costs. The FDA periodically inspects manufacturing facilities in the United States in order to assure compliance with applicable GMP requirements. Foreign manufacturers are also inspected by the FDA if their drugs are marketed in the United States. Failure of the foreign or domestic suppliers of the Company's products or failure of the manufacturers of the Company's products to comply with GMP regulations or other FDA regulatory requirements would have a material adverse effect on the Company's business, financial condition and results of operations.

The active compound in the Company's SuperVent(TM) product under development, tyloxapol, is presently manufactured for several third parties pursuant to GMP standards by an affiliate of Sanofi-Winthrop, Inc. ("Sanofi"), a multinational pharmaceutical company. Sanofi is the sole supplier of tyloxapol with GMP standard manufacturing capabilities and there are few alternative non-GMP approved sources of supply. The Company does not presently have an agreement with Sanofi to supply any additional material either in connection with a Phase III clinical trial or, following regulatory approval, for marketing purposes. In addition, the Company does not intend to enter into an agreement for supply of the formulated drug containing tyloxapol until the Company plans to initiate a Phase III clinical trial. There can be no assurance that the Company will be able to enter into a supply agreement with Sanofi or a supplier of the formulated drug on terms acceptable to the Company, if at all. In such case, the Company would be required to seek alternate manufacturing sources capable of producing tyloxapol and the formulated drug. There can be no assurance that the Company will be able to identify and contract with alternative manufacturers on terms acceptable to it, if at all. Any interruption in the supply of tyloxapol would have a material adverse effect on the Company's business, financial condition and results of operations. The Company has entered into an agreement with Cook Imaging Corporation for the packaging and storage, under sterile and stable conditions, of tyloxapol.

ATI has acquired from J&J experimental compounds, the KL4 peptides and manufacturing equipment needed to produce and meet the Company's requirements for clinical supplies of KL4-Surfactant. ATI has entered into an agreement with Cook Imaging Corporation for the development of the manufacturing process to be employed in the KL4-Surfactant program. ATI intends to seek an agreement with a third party manufacturer to produce KL4-Surfactant on an ongoing basis during 1997. There can be no assurance that agreement for such production will be reached. Failure to identify and reach an agreement with a third party manufacturer would substantially delay the Company's development of KL4-Surfactant and could have a material adverse effect on the Company's business, financial condition and results of operations.

The Company is in the process of negotiating an exclusive supply agreement with Tetrionics, Inc. ("Tetrionics") to manufacture and supply the Company with ST-630 for the Company's investigational and commercial purposes. Tetrionics presently manufactures and supplies ST-630 to Penederm, Inc. for investigational topical use for the treatment of psoriasis. There can be no assurance that the Company will be able to reach an agreement with Tetrionics on terms acceptable to the Company, if at all. Failure to achieve an agreement could substantially delay the Company's development of ST-630.

DEPENDENCE ON OTHERS FOR CLINICAL DEVELOPMENT OF, REGULATORY APPROVALS FOR AND MANUFACTURING AND MARKETING OF PHARMACEUTICAL PRODUCTS

The Company's strategy is to seek to enter into collaborative agreements with pharmaceutical companies for the research and development, clinical testing, manufacturing, marketing and commercialization of certain of its products. The Company will therefore be dependent upon the expertise and dedication of sufficient resources by third parties to develop and commercialize certain of its proposed products. The Company may in the future grant to its collaborative partners, if any, rights to license and commercialize any pharmaceutical products developed under these collaborative agreements and such rights would limit the Company's flexibility in considering alternatives for the commercialization of such products. Under such agreements, the Company expects to rely on its collaborative partners to conduct research and clinical trials,

9

manufacture, market and commercialize certain of its products. Although the Company believes that its collaborative partners may have an economic motivation to commercialize the pharmaceutical products which they may license from the Company, the amount and timing of resources devoted to these activities generally will be controlled by each such individual partner. There can be no assurance that the Company will be successful in establishing any collaborative arrangements, or that, if established, such future partners will be successful in developing and commercializing products or that the Company will derive any revenues from such arrangements.

The Company has recently entered into a clinical research agreement with the University of Utah Health Sciences Center for clinical trials of SuperVent(TM) in the treatment of CF. This Phase I/II clinical trial began on March 17, 1997.

ATI and Scripps have entered into a sponsored research agreement (the "Sponsored Research Agreement") supporting continuing research by Charles G. Cochrane, M.D., and Susan Revak of Scripps. Pursuant to the Sponsored Research Agreement, ATI will contribute $460,000 annually to Scripps' KL4-Surfactant research efforts for an initial two-year period. ATI has an option to acquire an exclusive worldwide license to make, have made, sell or use technology developed under the agreement, which it is required to exercise within 180 days from receipt of notice from Scripps of the development of such technology. Scripps will own all technology that it develops pursuant to work performed under the Sponsored Research Agreement. ATI has the right to receive 50% of the net royalty income received by Scripps for inventions jointly developed by ATI and Scripps to the extent ATI does not exercise its option with respect to such inventions. ATI has entered into consulting agreements with certain key research personnel at Scripps. See "Executive Compensation and Employment and Consulting Agreements."

The Company has not entered into any collaborative arrangements with respect to its ST-630 product.

LACK OF MARKETING CAPABILITY AND EXPERIENCE

It is the Company's long-term goal to manufacture and market SuperVent(TM) for CF and possibly certain of its other products through a direct sales force (or, in the case of CF, possibly through the distribution capabilities of the Cystic Fibrosis Foundation), if and when necessary regulatory approvals are obtained. The Company currently has no marketing and sales experience and no marketing or sales personnel. Unless a sales force is established, the Company will be dependent on corporate partners or other entities for the marketing and selling of its products. There can be no assurance that the Company will be able to enter into any satisfactory arrangements for the marketing and sale of its products. The inability of the Company to successfully establish a sales force or enter into third party distribution, marketing and selling arrangements for its anticipated products would have a material adverse effect on the Company's business, financial condition and results of operations.

DEPENDENCE UPON KEY PERSONNEL AND CONSULTANTS

The Company will be highly dependent upon its officers and directors, as well as its medical advisory board and scientific advisory board members, consultants and collaborating scientists. The management of the Company currently consists of 11 persons. The loss of the services of any of these individuals or of any of its medical advisory board or scientific advisory board members, consultants and/or collaborating scientists could have a material adverse effect on the Company's business, financial condition and results of operations. The Company has not obtained, and does not intend to obtain, key-man life insurance on any of its key personnel.

Since competent management personnel are in great demand, there can be no assurance that the Company will be able to attract and retain such personnel on a timely basis and on terms acceptable to the Company. The Company believes that its success will depend in large part upon attracting and retaining highly-skilled managerial and other employees.

10

NO ASSURANCE OF ADDITIONAL PRODUCTS; RISKS ASSOCIATED WITH CERTAIN DRUG CANDIDATES

Although the Company intends to devote substantial resources to the development and commercialization of SuperVent(TM), KL4-Surfactant and ST-630, it will explore the acquisition and subsequent development and commercialization of additional pharmaceutical products and technologies. There can be no assurance that the Company will be able to identify any additional products or technologies, that it will be able to license any such technologies on acceptable terms or that, even if suitable products or technologies are identified, the Company will have sufficient resources to pursue any such products or technologies to commercialization.

Each of the Company's products may represent risks that are presently unknown to the Company and which may be the basis of an adverse regulatory determination with regard to the development and commercialization of such products. Tyloxapol has been used in low concentrations by the pharmaceutical industry for over 40 years without any reported significant adverse effects. However, since SuperVent(TM) will likely be using a higher dosage of tyloxapol, the Company will have to demonstrate safety at a tyloxapol dose significantly higher than that used previously.

Preclinical studies of KL4-Surfactant have revealed no local or systemic toxicity associated with test material having KL4-Surfactant concentrations well in excess of those intended to be clinically tested. These studies also revealed a lack of mutagenicity and immunogenicity. However, the Company will have to demonstrate the effectiveness of KL4-Surfactant at a safe dosage level prior to marketing KL4-Surfactant for the treatment of MAS, ARDS and/or IRDS.

The Company will have to demonstrate the effectiveness of ST-630 at a safe dosage level in order to receive marketing approval in the United States for the treatment of postmenopausal osteoporosis. Prior studies of vitamin D analogs such as ST-630, which are administered in their active form, have been associated with hypercalcemia in a number of patients. Hypercalcemia is characterized by elevated calcium levels in the blood above a generally accepted range. The Company believes that this risk of hypercalcemia may be the primary reason why active vitamin D analogs have only been tested on a limited basis in the United States, which is generally considered to be a high calcium consumption country. The Company has not yet conducted the clinical studies that will be required to determine whether ST-630 presents this same risk of hypercalcemia. Although the Company believes that, based upon the results of prior studies of ST-630, this compound may have a higher potency and greater therapeutic window as compared to other active vitamin D analogs, there can be no assurance that the Company will be able to demonstrate a dosage level for ST-630 that will be both safe and effective.

CONTROL BY CURRENT OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS

The Company's directors, executive officers and principal stockholders beneficially own approximately 24.40% of the outstanding shares of Common Stock, assuming (a) the conversion of all outstanding shares of Series A Preferred Stock and assuming issuance of the shares of Common Stock (i) subject to the Common Placement Warrants and (ii) issuable upon conversion of the Series A Preferred Stock subject to the Preferred Placement Warrants and (b) the exercise of all outstanding vested options. Accordingly, the Company's executive officers, directors, principal stockholders and certain of their affiliates will have the ability to exert substantial influence over the election of the Company's Board of Directors and the outcome of issues submitted to the Company's stockholders. Such a concentration of ownership may have the effect of delaying or preventing a change in control of the Company, including transactions in which shareholders might otherwise recover a premium for their shares over their current market prices. See "Principal Stockholders."

COMPETITION

The Company is engaged in a highly competitive field of pharmaceutical research. Competition from numerous existing companies and others in respiratory, anti-inflammatory and anti-oxidant research and the fields of CF, MAS, ARDS, IRDS and postmenopausal osteoporosis is intense and expected to increase. In addition, the Company expects to compete with conventional pharmaceutical companies. Most of these companies have substantially greater research and development, manufacturing, marketing, financial, technological, personnel and managerial resources than the Company. Acquisitions of competing companies by large pharmaceutical or health care companies could further enhance such

11

competitors' financial, marketing and other resources. Moreover, competitors that are able to complete clinical trials, obtain required regulatory approvals and commence commercial sales of their products before the Company could have a significant competitive advantage. There can be no assurance that any products developed by the Company's competitors will not be more effective than any developed by the Company.

RISK OF PRODUCT LIABILITY; NO INSURANCE COVERAGE

Should the Company develop any products, the marketing of such products, through third party arrangements or otherwise, may expose the Company to product liability claims in the event that the use or misuse of pharmaceutical products manufactured by, or under license from, the Company results in adverse effects. The Company presently carries product liability insurance which covers adverse events in connection with its Phase I/II clinical trial of SuperVent(TM) at the University of Utah Health Science Center. The Company may be required to obtain additional product liability insurance coverage prior to initiation of clinical trials of its other proposed products. In addition, the Company intends to obtain product liability insurance coverage before commercialization of its proposed products. There can be no assurance that adequate insurance coverage will be available at an acceptable cost, if at all. In addition, there can be no assurance that a product liability claim, even if the Company has insurance coverage, would not materially adversely affect the Company's business, financial condition and results of operations.

UNCERTAINTY OF PRODUCT PRICING AND REIMBURSEMENT; HEALTH CARE REFORM AND RELATED MEASURES

The levels of revenues and profitability of pharmaceutical and/or biotechnology products and companies may be affected by efforts of governmental and third party payers to contain or reduce the costs of health care through various means. For example, in certain foreign markets, pricing or profitability of prescription pharmaceuticals is subject to government control. In the United States, there have been, and the Company expects that there will continue to be, a number of federal and state proposals to implement similar government control. Presently, the United States Congress is considering a number of legislative and regulatory reforms that may affect companies engaged in the health care industry in the United States. Pricing constraints on the Company's products, if approved, could have a material adverse effect on the Company. Although the Company cannot predict whether these proposals will be adopted or what effects such proposals may have on its business, the existence and pendency of such proposals could in general have a material adverse effect on the Company. In addition, the Company's ability to commercialize potential pharmaceutical and/or biotechnology products may be adversely affected to the extent that such proposals have a material adverse effect on other companies that are prospective collaborators with respect to any of the Company's product candidates.

In the United States and elsewhere, successful commercialization of the Company's products will depend in part on the availability of reimbursement to the consumer from third party health care payers, such as government and private insurance plans. There can be no assurance that such reimbursement will be available or will permit price levels sufficient to realize an appropriate return on the Company's investment in product development. Third party health care payers are becoming increasingly cost conscious in determining which pharmaceutical products they will and will not reimburse. If the Company succeeds in bringing one or more products to the market, there can be no assurance that these products will be considered cost effective and that reimbursement to the consumer will be available or will be sufficient to allow the Company to sell its products on a competitive basis. See "Risk Factors-- Extensive Government Regulation; Uncertainty of FDA and Other Governmental Approval of Products under Development."

CERTAIN INTERLOCKING RELATIONSHIPS; POTENTIAL CONFLICTS OF INTEREST

The Chairman of the Company is a full-time officer of Paramount. In addition, Kenneth Johnson, the Director of Business Development of the Company, is a Technology Associate of Paramount Capital Investments, LLC ("Paramount Investments"), an affiliate of Paramount. See "Management" and "Certain Transactions". Each of these individuals devotes only a portion of his time to the business of the Company. Paramount acted as placement agent for the Company in a private placement of its equity securities conducted during June through November 1996 (the "Unit Offering"), pursuant to which the Selling Securityholders acquired their Common Stock and Series A Preferred Stock. The Company currently shares its office space with Paramount. Paramount Investments is a merchant banking firm specializing in biotechnology companies. In the regular course of its business, Paramount Investments identifies, evaluates and pursues

12

investment opportunities in biomedical and pharmaceutical products, technologies and companies. Delaware corporate law requires that any transactions between the Company and any of its affiliates be on terms that, when taken as a whole, are substantially as favorable to the Company as those then reasonably obtained from a person who is not an affiliate in an arm's-length transaction. Nevertheless, Paramount Investments is not obligated pursuant to any agreement or understanding with the Company to make any additional products or technologies available to the Company, and there can be no assurance, and purchasers of the Common Stock should not expect, that any biomedical or pharmaceutical product or technology identified by Paramount Investments or any other affiliates of Paramount or Paramount Investments in the future will be made available to the Company. The Company maintains a policy that, subject to the approval of a majority of the disinterested directors of the Company, the Company may compensate directors of the Company in the form of cash bonuses and/or stock options, in connection with new drug candidates licensed or acquired by the Company which were identified and introduced to the Company by such persons. In addition, certain of the officers, directors, consultants, and advisors to the Company may from time to time serve as officers, directors, consultants or advisors to other biopharmaceutical or biotechnology companies. There can be no assurance that such other companies will not in the future have interests in conflict with those of the Company.

ABSENCE OF MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

To date, there has been no public market for the securities of the Company. The market price, if any, of the Common Stock, like that of many other development-stage public pharmaceutical or biotechnology companies, may be highly volatile. Factors such as announcements of technological innovations or new commercial products by the Company or its competitors, disclosure of results of preclinical and clinical testing, adverse reactions to products, governmental regulation and approvals, developments in patent or other proprietary rights, public or regulatory agency concerns as to the safety of any products developed by the Company and general conditions may have a significant or adverse effect on the market price of the Common Stock.

UNCERTAINTY OF LISTING ON NASDAQ SMALL-CAP MARKET; POSSIBLE DELISTING FROM NASDAQ SMALL-CAP MARKET; MARKET ILLIQUIDITY

The Company intends to apply for listing of the Common Stock on the Nasdaq Small-Cap Market under the symbol "DSCO". The Company believes that it will meet the currently proposed criteria for such listing on such market at the time of effectiveness of the registration statement of which this Prospectus is a part, including, without limitation: (i) net tangible assets of at least $4 million;
(ii) an operating history of over one year; (iii) a market value of its publicly held shares of at least $5 million; (iv) at least 300 holders of the Common Stock; (v) at least three market makers; and (vi) and an initial minimum bid price of at least $4.00. However, there can be no assurance that the Common Stock will be listed on the Nasdaq Small-Cap Market. The prices of the Common Stock which may be obtained on the Nasdaq Small-Cap Market are not necessarily related to the Company's assets, book value, results of operations or any other established criteria of value, and should not be regarded as any indication of future market price of the Common Stock.

Assuming the Nasdaq Small-Cap Market listing of the Common Stock is approved, continued inclusion of the Common Stock on the Nasdaq Small-Cap Market is proposed to require: (i) that the Company maintain at least $2,000,000 in net tangible assets, a market capitalization of $35 million or $500,000 of net income in two out of three years; (ii) a market value of its publicly held shares of at least $1 million; (iii) that the minimum bid price for the Common Stock be at least $1.00 per share; (iv) that the public float of the Common Stock consist of at least 500,000 shares; (v) that the Common Stock have at least two active market makers; and (vi) that the Common Stock be held by at least 300 holders. If the Company is unable to satisfy such maintenance requirements, the Common Stock may be delisted from the Nasdaq Small-Cap Market. In such event, trading, if any, in the Common Stock would thereafter be conducted in the over-the-counter market in the "pink sheets" or the OTC Bulletin Board. Consequently, the liquidity of the Common Stock could be materially and adversely impaired, not only in the number of securities that can be bought and sold at a given price, but also through delays in the timing of transactions and reduction in security analysts' and the media's coverage of the Company, which could result in lower prices for the Common Stock than might otherwise be attained and could also result in a larger spread between the bid and asked prices for the Common Stock. See "Risks of Low Price Stock; Possible Effect of "Penny Stock" Rules on Liquidity for the Common Stock."

RISKS OF LOW-PRICED STOCK; POSSIBLE EFFECT OF "PENNY STOCK" RULES ON LIQUIDITY FOR THE COMMON STOCK

The Securities Exchange Act of 1934, as amended (the "Exchange Act") requires additional disclosure relating to the market for penny stocks in connection with trades in any stock defined as a penny stock. The Commission's regulations generally define a penny stock to be any equity security that has a market price of less than $5.00 per share, subject to certain exceptions. Such exceptions include any equity security listed on a national securities exchange or quoted on Nasdaq and any equity security issued by an issuer that has (i) net tangible assets of at least $2 million, if such issuer has been in continuous operation for three years, (ii) net tangible assets of at least $5 million, if such issuer has been in continuous operation for less than three years, or (iii) average annual revenue of at least $6 million, if such issuer has been in continuous operation for less than three years. There can be no assurance that the Company will meet the requirements of the foregoing exceptions.

In addition, if the Company's securities are not listed on a national securities exchange or quoted on Nasdaq or fail to meet the net tangible asset or annual revenue tests set forth above, but are quoted on the OTC Bulletin Board (as to which there can be no assurance), then trading in the Company's securities would be regulated pursuant to Rules 15-g-1 through 15-g-6 and 15-g-9 promulgated under the Exchange Act for non-Nasdaq and non-exchange listed securities. Under such rules, broker-dealers who recommend such securities to persons other than established customers and "accredited investors" must make a special written suitability determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written agreement to this transaction. Consequently, such Exchange Act rules may affect the ability of broker-dealers to make a market in such shares and may affect the ability of holders of Common Stock to sell such stock in the secondary market. Securities are exempt from these rules if the market price of such securities is at least $5.00 per share.

Unless exempt, the rules require delivery, prior to any transaction in a penny stock, of a disclosure schedule prepared by the Commission relating to the penny stock market. Disclosure is also required to be made about sales commissions payable to both the broker-dealer and the registered representative and current quotations for the securities. Finally, monthly statements are required to be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks.

If the Common Stock is subject to the rules on penny stocks, the market liquidity for such securities could be materially and adversely affected.

POTENTIAL ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE

As of December 13, 1996, 6,712,256 shares of Common Stock were issued and outstanding, 4,512,000 of which the Company believes are "restricted securities" and under certain circumstances may, in the future, be sold in compliance with Rule 144. Assuming the availability of Rule 144, the Company believes that of the outstanding shares of Common Stock, 1,132,500 "restricted" shares of Common Stock are currently eligible for sale and up to 3,379,500 "restricted" shares will be eligible in 1998 and 1999, in each case subject to certain volume limitations and manner of sale requirements imposed by Rule 144. In general, under Rule 144, subject to the satisfaction of certain other conditions, a person, including an affiliate of the Company, who beneficially owned restricted shares of Common Stock for at least two years is entitled to sell, within any three-month period, a number of shares that does not exceed the greater of one percent of the total number of outstanding shares of the same class, or if the Common Stock is quoted on Nasdaq, a national securities exchange or the OTC Bulletin Board, the average weekly trading volume during the four calendar weeks immediately preceding the sale. A person who presently is not and who has not been an affiliate of the Company for at least three months immediately preceding the sale and who has beneficially owned the shares of Common Stock for at least three years is entitled to sell such shares under Rule 144(k) without regard to the volume limitations described above. In addition, the Company currently has issued and outstanding options to purchase an aggregate of 685,500 shares of Common Stock (excluding the Placement Agent Warrants), 481,125 of which are subject to vesting over the next 33 months. The Commission has recently adopted revisions to Rule 144 and Rule 144(k), the effect of which will be to shorten the holding period under Rule 144 from two years to one year and to shorten the holding period under Rule 144(k) from three years to two years.

14

No prediction can be made as to the effect, if any, that sales of shares of Common Stock or the availability of such shares for sale will have on the market prices that may be quoted from time to time on the OTC Bulletin Board, or Nasdaq if quoted thereon. Nevertheless, the possibility that substantial amounts of Common Stock may be sold in the public market may adversely effect the prevailing market prices for the Common Stock and could impair the Company's ability to raise capital in the future through the sale of equity securities. Actual sales or the prospect of future sales of shares of Common Stock under Rule 144 or otherwise may have a depressive effect upon the price of the Common Stock and the market therefor.

ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND DELAWARE LAW

The Company's Certificate of Incorporation, as amended, authorizes the issuance of up to 10,000,000 shares of preferred stock, of which 2,200,256 shares are currently outstanding (without giving effect to any shares issuable upon exercise of the Placement Agent Warrants). The Board of Directors has been granted the authority to fix and determine the relative rights and preferences of preferred shares, as well as the authority to issue such shares, without further stockholder approval. As a result, the Board of Directors could authorize the issuance of a series of preferred stock which would grant to holders the preferred right to the assets of the Company upon liquidation, the right to receive dividend coupons before dividends would be declared to Common Stockholders, and the right to the redemption of such shares, together with a premium, prior to the redemption of Common Stock. Common stockholders have no redemption rights. In addition, the Board could issue large blocks of preferred stock to fend against unwanted tender offers or hostile takeovers without further shareholder approval. See "Description of Securities." The Company is subject to Section 203 of the General Corporation Law of the State of Delaware which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that such stockholder became an interested stockholder. In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person. The foregoing provisions could have the effect of discouraging others from making tender offers for the Company's shares and, as a consequence, they also may inhibit fluctuations in the market price of the Company's shares that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in the management of the Company.

DIVIDENDS UNLIKELY

The Company has never paid cash dividends on its capital stock and does not anticipate paying any cash dividends for the foreseeable future.

POTENTIAL CONVERSION PRICE RESET OF SERIES A PREFERRED STOCK

Pursuant to the Unit Offering, the Company consummated an offering of Units consisting of Series A Preferred Stock and Common Stock. 2,200,256 shares of Series A Preferred Stock were included in the Units sold in the Unit Offering. Shares of Series A Preferred Stock are convertible at the option of the holders thereof into shares of Common Stock of the Company, at an initial conversion rate corresponding to a conversion price equal to $2.50 per share. The conversion price in effect immediately prior to the date that is 12 months after the first date on which the shares of Common Stock are publicly traded (the "Reset Date") will be adjusted effective as of the Reset Date if the average closing bid price of the Common Stock for the 30 consecutive trading days immediately preceding the Reset Date is less than 135% of the then applicable conversion price. Any such reset of the conversion price applicable to the Series A Preferred Stock would have a dilutive effect on purchasers of the Common Stock offered hereby.

FORWARD LOOKING STATEMENTS

Certain of the statements set forth in this Prospectus, including, without limitation, the Company's research and development programs, the seeking of joint development or licensing arrangements with pharmaceutical companies, the research and development of particular compounds and technologies for particular indications and the period of time for which the Company's existing resources will enable the Company to fund its operations and to meet the initial listing requirements for the quotation of its securities on the Nasdaq Small-Cap Market, are forward-looking and based upon the

15

Company's current belief as to the outcome, occurrence and timing of future events or current expectations and plans. All such statements involve significant risks and uncertainties. Many important factors affect the Company's ability to achieve the stated outcomes and to successfully develop and commercialize its product candidates including, among other things, the ability to obtain substantial additional funds, to obtain and maintain all necessary patents or licenses, to demonstrate the safety and efficacy of product candidates at each state of development, to meet applicable regulatory standards and receive required regulatory approvals, to meet obligations under its license agreements, to be capable of producing drug candidates in commercial quantities at reasonable costs, to successfully compete against other products and to market products in a profitable manner. As a result, there also can be no assurance that these statements included in the Prospectus will prove to be accurate. In light of the significant uncertainties inherent in these statements included herein, the inclusion of such information should not be regarded as a representation by the Company or any other person that the objectives and plans of the Company will be achieved.

(1) Does not include 220,026 shares of Series A Preferred Stock issuable upon exercise of the Preferred Placement Warrants which were issued to the Placement Agent and/or its designees in connection with the Unit Offering. See "Certain Transactions" and "Description of Securities--Placement Agent Warrants."

(2) Does not include options to purchase up to 685,500 shares of Common Stock held by certain directors, officers and employees of the Company. Excludes an additional aggregate of 1,100,129 shares of Common Stock issuable upon exercise of the Common Placement Warrants and issuable upon conversion of Series A Preferred Stock issuable upon exercise of the Preferred Placement Warrants, which warrants were in each case issued to the Placement Agent and/or its designees in connection with the Unit Offering.

17

USE OF PROCEEDS

The Company will not receive any proceeds from the sale of shares of Common Stock. The Company is not expected to receive any proceeds from the exercise of the Placement Agent Warrants since the Placement Agent Warrants may be exercised pursuant to cashless exercise provisions. In the event that the Placement Agent Warrants are exercised for cash, the Company intends to use such net cash proceeds (after estimated offering expenses of this Offering of approximately $300,000) for general working capital purposes. Proceeds, if any, from the exercise for cash of all the Placement Agent Warrants, before deduction of estimated expenses of this Offering, would be approximately $2,475,000. Whether, how and to what extent any of the Placement Agent Warrants will be exercised, and whether the Placement Agent Warrants are exercised for cash or not, cannot be predicted by the Company.

DIVIDEND POLICY

The Company has not paid any cash dividends on its Common Stock since its formation. The payment of dividends, if any, in the future, with respect to the Common Stock, is within the discretion of the Board of Directors of the Company and will depend on the Company's earnings, capital requirements, financial condition and other relevant factors. The Board of Directors of the Company does not presently intend to declare any dividends on the Common Stock in the foreseeable future.

The Company anticipates that all earnings and other resources of the Company, if any, will be retained by the Company for investment in its business.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND PLAN OF OPERATIONS

GENERAL

The Company was originally organized as MicroBio, Inc. on May 18, 1993. The Company had limited operations prior to January 1995. In May 1996, the Company amended its Certificate of Incorporation to effect a name change to its current name, Discovery Laboratories, Inc. In April 1996, the Company entered into a three-year employment agreement with James S. Kuo, M.D., whereby Dr. Kuo agreed to serve as President and Chief Executive Officer of Discovery. In October 1996, ATI entered into a four-year employment agreement with Robert J. Capetola, Ph.D., whereby Dr. Capetola became the President, Chief Executive Officer and Chairman of the Board of ATI.

Since its inception, the Company has concentrated its efforts and resources in the development and commercialization of pharmaceutical products and technologies. The Company has been unprofitable since its founding and has incurred a cumulative net loss of approximately $3,254,000 as of December 31, 1996. The Company expects to incur significantly increasing operating losses over the next several years, primarily due to the expansion of its research and development programs, including clinical trials for the SuperVent(TM) and ST-630 products, the KL4-Surfactant technology and other products and technologies that it may acquire or develop. The Company's ability to achieve profitability depends upon, among other things, its ability to discover and develop products, obtain regulatory approval for its proposed products, and enter into agreements for product development, manufacturing and commercialization. None of the Company's products currently generate revenues and the Company does not expect to achieve revenues for the foreseeable future. Moreover, there can be no assurance that the Company will ever achieve significant revenues or profitable operations from the sale of the SuperVent(TM) and ST-630 products, the KL4-Surfactant technology or any other products or technologies that it may acquire or develop. See "Risk Factors--Development Stage Company; No Developed or Approved Products; Uncertainty of Future Profitability."

PLAN OF OPERATION

The Company is currently engaged in the development and commercialization of investigational drugs that have previously been tested in humans or animals. In March 1996, the Company executed a license agreement with CMHA as owner and licensor of the Company's tyloxapol patents and patent applications. The Company paid $86,400 as a license issue fee to CMHA to obtain its license, which fee was capitalized and is being amortized over the term of the license. In September 1996, the Company entered into a license agreement (the "WARF License Agreement") with WARF relating to an active vitamin D analog, ST-630, and its potential use in treating postmenopausal osteoporosis. The Company paid a $400,000 initial fee to WARF upon execution of the WARF License Agreement. In October 1996, ATI executed a sublicense agreement with J&J and J&J's wholly-owned subsidiary, Ortho Pharmaceutical Corporation, granting an exclusive sublicense of the KL4-Surfactant technology to ATI in exchange for an initial $200,000 license fee, additional milestone payments, royalties and common stock of ATI. J&J is contributing its existing KL4-Surfactant raw material inventory and specialized manufacturing equipment, with an estimated original cost of $3.3 million, to ATI in exchange for shares of nonvoting Series B Preferred Stock of ATI having a $2.2 million liquidation preference.

The Company anticipates that during the next 12 months it will conduct substantial research and development of the SuperVent(TM), KL4-Surfactant and ST-630 products, including, without limitation, a Phase I/II clinical trial of SuperVent(TM) for the treatment of CF that was commenced on March 17, 1997 (and, assuming the successful completion of such clinical trial, a Phase II clinical trial of SuperVent(TM) for the treatment of chronic bronchitis) and Phase II clinical trials of KL4-Surfactant for the treatment of MAS and ARDS. The Company also intends to initiate clinical studies of ST-630 as a once-daily, orally administered drug for the treatment of postmenopausal osteoporosis in the United States during the next 12 months. Certain of the planned clinical trials of the Company's products in development require the receipt of FDA approvals, and there can be no assurance as to the receipt or the timing of receipt of such approvals. See "Business--Products and Technologies Under Development," and "--Government Regulation; Orphan Drug Designation." The Company may seek to acquire additional products and technologies in the future. Should the Company acquire such additional products or technologies, it is anticipated that such additional products or technologies will require substantial resources for research, development and clinical evaluation. However, there can be no assurance that the Company will be able to obtain the additional financing necessary to acquire and develop such products and technologies. Furthermore, there can be no assurance

19

that changes in the Company's research and development plans or other changes which would or could alter the Company's operating expenses will not require the Company to reallocate funds among its planned activities and curtail certain planned expenditures. In such event, the Company may need additional financing. There can be no assurance as to the availability or the terms of any required additional financing, when and if needed. In the event that the Company fails to raise any funds it requires, it may be necessary for the Company to significantly curtail its activities or cease operations.

The Company has recently hired seven new employees to serve as Vice President of Clinical Affairs, Vice President of Regulatory Affairs, Director of Business Development and Project Manager, respectively, of Discovery, and Vice President of Biometrics, Vice President of Clinical Research and Director of Clinical Research, respectively, of ATI. The timing and cost of hiring any additional employees may vary depending on need and cannot currently be predicted with any certainty.

ATI has entered into an agreement with Cook Imaging Corporation for the development of the manufacturing process to be employed in the KL4-Surfactant program. It is also anticipated that, over the next 12 months, ATI will enter into an agreement with a third party for the purpose of supplying KL4-Surfactant to ATI. No specific supplier has been identified to date.

LIQUIDITY AND CERTAINTY

The Company anticipates that its current resources will permit it to meet its business objectives until approximately June 1998. The Company's working capital requirements will depend upon numerous factors, including, without limitation, progress of the Company's research and development programs, preclinical and clinical testing, timing and cost of obtaining regulatory approvals, levels of resources that the Company devotes to the development of manufacturing and marketing capabilities, technological advances, status of competitors and abilities of the Company to establish collaborative arrangements with other organizations, and as such there can be no assurance that the Company will not be required to raise additional capital prior to June 1998 or, in general, that the Company will be able to achieve its business objectives.

The Company experienced a substantial increase in expenses during 1996 as compared to earlier periods due to expenses incurred in connection with the Unit Offering. See "Certain Transactions."

BUSINESS

Discovery Laboratories, Inc. ("Discovery" and together with its majority-owned subsidiary, Acute Therapeutics, Inc. ("ATI"), the "Company") is a development stage pharmaceutical company that is focused on acquiring, developing and commercializing proprietary, investigational drugs that have previously been tested in humans or animals. The Company's strategy is to conduct preclinical and clinical studies on investigational drugs licensed from third parties, either alone or in collaboration with corporate partners. The Company may also seek to enter into collaborations with corporate partners for manufacturing and marketing of such drugs.

PRODUCTS AND TECHNOLOGIES UNDER DEVELOPMENT

SUPERVENT(TM)

BACKGROUND

The Company is developing SuperVent(TM) as a stable aerosolized, multidimensional therapy for airway diseases characterized by inflammation, injurious oxidation and excessive sputum. SuperVent's(TM) active compound is tyloxapol, a non-anionic, alkylaryl polyether alcohol polymer which has been safely used as an emulsifying agent in drug formulations by the United States pharmaceutical industry for over 40 years. Tyloxapol is a slightly viscous, amber liquid that is slowly but freely soluble in water and has a pleasant, slightly aromatic odor. The compound is generally recognized as relatively non-toxic to human cells and the mammalian lung. Tyloxapol had no reported respiratory toxicity in rhesus monkeys when administered daily by aerosol for a year at 15% weight/volume. The compound is not orally absorbed. Experimental research conducted by the Company's scientific founders has led to the discovery that tyloxapol appears to possess biological activities beyond its well-recognized emulsification properties. Tyloxapol is thought to have three mechanisms of action:

o Anti-inflammatory activity

o Anti-oxidant activity

o Mucolytic activity

The combination of the above pharmacologic activities is not presently found in any single, safe, effective therapy for cystic fibrosis or chronic bronchitis. If successfully developed and approved, SuperVent(TM) is intended to be used daily by cystic fibrosis and chronic bronchitis patients in the home and hospital to preserve pulmonary function and aid mucus expectoration.

The Company has obtained an exclusive, worldwide license from The Charlotte-Mecklenburg Hospital Authority ("CMHA") which covers two issued United States patents and two pending United States and corresponding foreign patent applications relating to pharmaceutical preparations containing high concentrations of tyloxapol and the use of tyloxapol for the treatment of a variety of respiratory and other diseases involving inflammation and oxidative damage. The United States Food and Drug Administration (the "FDA") has granted orphan drug status for the use of tyloxapol to treat cystic fibrosis ("CF"). See "Government Regulation; Orphan Drug Designation." The Company has commenced clinical testing of SuperVent(TM) for the treatment of CF and intends to clinically test SuperVent(TM) for the treament of chronic bronchitis. Because Phase I clinical studies of tyloxapol have not been completed, the Company has not yet determined what adverse effects, if any, may be produced by tyloxapol at the concentrations in which it will be present in the Company's SuperVent(TM) product.

CYSTIC FIBROSIS AND ITS PATHOLOGY

CF is a progressive, lethal respiratory disease that occurs in about one out of every 2,000 live births in the United States and Europe. CF afflicts approximately 23,000 patients in the United States and a comparable number in Europe. It is the most common lethal genetic disease among Caucasians. A revolutionary improvement in the medical management of CF has allowed most patients with the disease to live until the age of 29. The progressive destruction of CF lungs is the major

21

impediment to even longer survival and improved health. A new therapy which minimizes the pulmonary complications of CF would have a major impact on the length and quality of life of its patients.

CF results from a genetic defect in the CFTR gene. The CFTR gene codes for a membrane protein responsible for the transport of chloride ions. Because of this genetic defect, CF mucus is excessively viscous and adherent to airway walls. Destruction of the lungs of CF patients occurs gradually as the inability to clear mucus from the lungs leads to blockage of the airways usually beginning in the smaller airways and alveoli. Impacted mucus traps foreign particles and pathogens and becomes a source of bacterial colonization, typically with PSEUDOMONAS AERUGINOSA ("PSEUDOMONAS"). The patient's immune system responds to the chronic infection by sending macrophages into the airways which recognize and attempt to destroy the bacteria. These macrophages then recruit legions of neutrophils to the lungs which activate the inflammatory transcriptional factor Nuclear Factor-kappa B ("NF-[kappa]B") and initiate a cytokine-mediated inflammatory response. The activated immune cells secrete inflammatory cytokines, oxidative chemicals and destructive enzymes into the lungs. Repeated inflammatory and oxidative processes initiated by macrophages and neutrophils to clear the infection are typically ineffective and result in collateral damage to the alveoli and small airways. Destroyed airway cells, neutrophils and macrophages then spill their DNA and actin into the alveoli and markedly increase the viscosity and adhesiveness of airway sputum. This debris-laden mucus, rich in proteases and oxidants, causes the alveoli to collapse and are then replaced with nonfunctional fibrous tissue. Eventually, a critical number of alveoli, small airway cells and large airway cells are destroyed so that the respiratory function of CF patients becomes insufficient to sustain life.

CLINICAL DEVELOPMENT PLAN FOR SUPERVENT(TM) FOR CF

The Company's clinical development plan for SuperVent(TM) is to focus first on CF, for which few safe and effective therapies exist. The Company has completed a clinical research agreement with the University of Utah Health Sciences Center ("UHSC") and has commenced a clinical trial pursuant to such agreement. The principal investigator of this clinical trial is Bruce C. Marshall, M.D., Director of the CF center of the UHSC. The co-investigators are John R. Hoidal, M.D., Chief of the Pulmonary and Pediatric Pulmonary Divisions at UHSC, and Wayne Samuelson, M.D., Director of the asthma center at UHSC. In September 1995, the FDA approved, subject to certain modifications, Dr. Hoidal's physician-sponsored Investigational New Drug ("IND") application to begin this trial. The trial is designed to determine whether aerosolized SuperVent(TM) holds promise as a low toxicity, anti-inflammatory, anti-oxidant and mucolytic agent for the treatment of CF. The specific aims of the initial clinical study, which is presently designed in three parts, are as follows:

PART A. A dose-ranging study will be performed in ten normal human volunteers receiving 4 ml of aerosolized SuperVent(TM) once daily to confirm a lack of airway toxicity and establish the safe inhaled concentration of SuperVent(TM). Assessment of outcomes will include various measures of respiratory function.

PART B. An open study will be undertaken to establish the effects of aerosolized SuperVent(TM) airway physiology and lung inflammation in ten patients with cystic fibrosis. Patients will be followed for two weeks while receiving 4 ml of aerosolized SuperVent(TM) once daily. Assessment of outcomes will include various measures of respiratory function.

PART C. In the format of a six-week, multi-center, randomized, double-blinded, placebo-controlled trial, 4 ml of aerosolized SuperVent(TM)once daily will be studied in up to 120 patients with cystic fibrosis with measures of outcome including respiratory function and physical exercise criteria.

The Company began the aforementioned Phase I/II clinical trial for the treatment of CF on March 17, 1997 at UHSC. Assuming the successful completion of the Phase I/II trial, the Company intends to commence a multi-center, randomized, double-blinded, placebo-controlled, Phase III clinical trial in CF and to file an additional IND to commence a Phase II clinical trial for the treatment of chronic bronchitis.

COLLABORATION WITH THE CYSTIC FIBROSIS FOUNDATION

The Company is collaborating with the Cystic Fibrosis Foundation in assembling a CF medical advisory board to advise on the design of the Phase I/II clinical trial in CF. The Cystic Fibrosis Foundation does not endorse investigational drugs but does lend its support to companies conducting clinical trials in CF. If successful in obtaining such support, the Company intends

22

to utilize the assistance of the Cystic Fibrosis Foundation's patient registry to coordinate a multi-center Phase III clinical trial. If the Phase III trial is successful and regulatory approval to market SuperVent(TM) is obtained, the Company plans to utilize the Cystic Fibrosis Foundation to distribute the product in the United States and Canada.

CURRENT RESPIRATORY THERAPIES FOR CYSTIC FIBROSIS

SUPPORTIVE CARE AND TRADITIONAL DRUG THERAPIES

The standard treatment for enhancing expectoration of CF sputum is postural drainage and chest percussion. In this daily procedure, patients lie in an inclined position with their head below their chest. The patient's chest is then repeatedly and gently pounded for several minutes with a cupped hand by a care giver. While modestly efficacious, postural drainage and chest percussion is labor intensive and requires a care giver.

When mucus becomes colonized with bacteria such as PSEUDOMONAS and other pathogens, a variety of intensive oral, intravenous and aerosolized antibiotics are administered. Repeated use of these antibiotics to clear the infection often results in strains of PSEUDOMONAS which are resistant to the antibiotics. Over time, many CF patients become chronically colonized with drug resistant PSEUDOMONAS. The ensuing cytokine-mediated inflammatory and oxidative process then accelerates the destruction of the lungs.

PULMOZYME(TM)

Standard daily pharmacologic therapy for airway obstruction in CF presently consists largely of inhaled Pulmozyme(TM) (recombinant human rhDNase or dornase alfa). This drug has been marketed by Genentech in the United States and Canada since early 1994. Pulmozyme(TM) reduces the viscosity of CF mucus by cleaving the DNA released from destroyed inflammatory, epithelial and bacterial cells which collect in mucus and contribute to its abnormal viscosity and adherence. The drug provides a small improvement in lung function and a slight reduction in the number of days requiring intravenous antibiotics for respiratory infections. The approximate yearly cost of Pulmozyme(TM) treatment for an average patient is $11,000. Genentech's 1995 sales of Pulmozyme(TM) are estimated to have been approximately $110 million.

LUNG TRANSPLANT

Lung transplantation is the final option for CF patients suffering from severely compromised respiratory function. However, there is an extremely limited supply of transplantable lungs and the operation is very costly. In addition, there is an increased risk of death from such a major surgical procedure and a long and painful recovery. Furthermore, patients who do recover must take immunosuppressive drugs for the rest of their life to prevent organ rejection, making them vulnerable to infections.

SUPERVENT(TM) FOR CHRONIC BRONCHITIS

Assuming the successful completion of the Phase I/II trial of SuperVent(TM) in CF, the Company intends to file an IND to commence a Phase II clinical trial for the use of SuperVent(TM) to treat chronic bronchitis. Chronic bronchitis is a major medical problem that is characterized by inflammation of the airways leading to cough and increased mucus production. The condition afflicts approximately 14,000,000 patients in the United States. Two primary causes of chronic bronchitis are habitual smoking and air pollution. Non-specific irritants contained in cigarette smoke and air pollution result in an increased number of macrophages entering into the lungs. The macrophages become activated and secrete inflammatory cytokines which recruit neutrophils that together release oxidants and elastase, an enzyme which degrades a structural component of the lungs, elastin. These released oxidants and free radicals oxidize alpha1-antitrypsin which normally inactivates elastase. In addition, elastin repair may be inhibited by cigarette smoke leading to structural changes in the lung that may significantly compromise respiratory function.

Based on clinical studies and other studies conducted by persons affiliated and unaffiliated with the Company, the Company believes that high concentrations of tyloxapol may improve pulmonary function in chronic bronchitis patients. SuperVent's(TM) active compound , tyloxapol, is also a component of Exosurf(TM), a product that has been clinically tested to treat chronic bronchitis. The chemical composition of the Company's SuperVent(TM) product is substantially different from that of Exosurf(TM). SuperVent(TM) contains a substantially higher concentration of tyloxapol in a phosphate-

23

buffered saline solution. Exosurf(TM) is composed of tyloxapol, cetyl alcohol, dipalmetoylphosphatitylcholine and sodium chloride. Exosurf(TM), as prepared for use in treating chronic bronchitis, was, to the Company's knowledge, difficult to satisfactorily aerosolize. SuperVent(TM) can be aerosolized and successfully delivered through a nebulizer.

HISTORY OF SAFE USE

Tyloxapol has been safely used by the pharmaceutical industry for over 40 years as an emulsifying agent in various drug formulations containing concentrations of tyloxapol lower than those intended to be present in the Company's SuperVent(TM) product. Sterling Pharmaceuticals ("Sterling") previously marketed in the United States a formulation containing low concentrations of tyloxapol (0.125% by volume) as an expectorant for chronic bronchitis under the trade name Alevaire(TM). Alevaire(TM) was first approved for use in the United States in the late 1940's in children with pulmonary tuberculosis as an aerosol delivery vehicle for streptomycin, an antibiotic. At that time, IN VITRO (i.e., non- animal) studies indicated that sodium bicarbonate and tyloxapol increased susceptibility of tuberculosis to streptomycin. Alevaire(TM) has been inhaled by children with tuberculosis for two hours a day for up to six months without adverse effects. In a group of adult tuberculosis patients, Alevaire's(TM) expectorant properties were noted when it was reported that thick, viscous mucus became thin and watery upon administration. Alevaire(TM) has been used as a mucolytic treatment for a variety of respiratory conditions. Based on published literature, Alevaire(TM) has no reported adverse effect on bacterial host-defense mechanisms and has even been locally infused into humans to hasten resolution of infected joints and pacemaker pockets.

Alevaire's(TM) marketing was discontinued by Sterling in 1981. At that time, passage of the Harris-Kefauver amendment to the Food and Drug Act mandated that older drugs previously approved only on the basis of safety, the regulatory standard at the time, were required to demonstrate efficacy to continue to be marketed. Because only anecdotal reports of efficacy and not controlled studies were available to support Alevaire's(TM) use in respiratory diseases, it was ruled that there was insufficient data to permit the product's continued use without further studies. Sterling apparently elected to withdraw the drug from the United States market, presumably because its patent had expired. Alevaire(TM) is still marketed in Japan by Nippon Shoju Co., Ltd. At the present time, tyloxapol, in addition to being used in the surfactant Exosurf(TM), is included as an "inactive" ingredient in the over-the-counter medications Vicks Sinex(TM) and Visex(TM), which are marketed by Procter & Gamble, Inc. A review of the literature by the Company does not indicate that Alevaire(TM) was ever tested as an anti-oxidant or used to treat CF.

MECHANISMS OF ACTION

ANTI-INFLAMMATORY ACTIVITY

Experimental studies suggest that SuperVent(TM) is a potent inhibitor of the inflammatory transcriptional factor NF-[kappa]B. Inhibition of NF-[kappa]B is an area of intense pharmaceutical research as it is a central transcriptional regulation element by which monocytes and macrophages regulate the expression of multiple inflammatory cytokines and growth factors implicated in the destruction of CF lungs. In preclinical studies, secretion of TNF-[alpha], IL-1(beta), IL-6, IL-8 and GM-CSF by LPS-stimulated human monocytes was significantly (p <0.010) decreased by tyloxapol in a dose-dependent manner.

ANTI-OXIDANT ACTIVITY

IN VITRO and IN VIVO (i.e., animal) experimental studies conducted by the Company's scientific founders suggest that SuperVent(TM) is a potent anti-oxidant capable of scavenging injurious hydroxyl radicals and hypochlorous acid. These toxic chemicals are produced in abundance by activated inflammatory cells in the airway. Two IN VITRO models testing the oxidant scavenging activity of tyloxapol showed that the addition of tyloxapol to the reaction mixture inhibited oxidant generation in a concentration dependent manner. In an additional IN VITRO model, tyloxapol was shown to be an effective oxidant scavenger through its ability to prevent oxidant-mediated conversion of diethanolamine to its corresponding chloramine. The Company's scientific founders have further shown in an IN VIVO model that tyloxapol protects against oxidant-mediated lung injury. Intratracheal instillation of oxidants in rats caused acute lung injury as demonstrated by a marked increase in protein concentration and neutrophil percentage in lung lavage fluid. Post-exposure treatment with tyloxapol significantly reduced both lavage protein concentration (p < 0.001) and neutrophil percentage (p < 0.010).

24

MUCOLYTIC ACTIVITY

IN VITRO studies of the sputum from CF patients suggest that the surface tension reducing properties of SuperVent(TM) may be an effective agent in decreasing mucus adherence and facilitating expectoration. The Company believes that SuperVent's(TM) ability to modify the biophysical properties of the abnormally thick mucus in CF patients should, in concert with postural percussion and drainage, offer respiratory benefit.

KL4-SURFACTANT TECHNOLOGY

BACKGROUND

Lung surfactants are protein-phospholipid complexes which coat the alveoli (air sacs) of the lungs. Alveoli are delicate, balloon-like sacs in the lungs where gaseous exchange occurs. Lung surfactants lower surface tension in expiration and raise it during inspiration to prevent the collapse of alveoli. Replacement surfactants are currently used mainly to treat infant respiratory distress syndrome ("IRDS"). Infants with this condition, as well as infants born with meconium in their lungs, which can lead to meconium aspiration syndrome ("MAS"), and patients with adult respiratory distress syndrome ("ARDS"), typically suffer from insufficient surfactant that leads to a life-threatening loss of pulmonary function.

KL4-Surfactant is a proprietary, synthetic lung surfactant that was originally invented at The Scripps Research Institute ("Scripps") by Charles G. Cochrane, M.D., et al. KL4-Surfactant is an aqueous suspension of lipid vesicles containing the novel synthetic peptide KL4 (KLLLLKLLLLKLLLLK). The "K" represents the water-soluble amino acid lysine and the "L" represents the fat-soluble amino acid leucine. KL4-Surfactant is patterned after human Surfactant Protein B, shown to have the greatest surfactant activity in humans . Human Surfactant Protein B acts by forming a stable monolayer on the inner surface of the pulmonary alveoli and preventing their collapse. The product was exclusively licensed to Johnson & Johnson, Inc. ("J&J"), which led its development from 1991 until its license to ATI. J&J completed a multi-center, Phase II clinical trial of KL4-Surfactant in 47 infants with IRDS. This trial demonstrated safety and efficacy comparable to that of the bovine-derived surfactant, Survanta(TM), markete by Ross Laboratories.

Discovery's majority-owned subsidiary, ATI, has acquired the exclusive worldwide sublicense to the KL4-Surfactant technology from J&J and J&J's wholly owned subsidiary, Ortho Pharmaceutical Corporation ("Ortho"). The Company believes that as a peptide-containing, synthetic lung surfactant, KL4-Surfactant will be superior to the non- protein-containing surfactant, Exosurf(TM), marketed by Glaxo-Wellcome. The Company further believes that KL4- Surfactant will be as effective as or superior to the animal-derived, protein-containing surfactants, Survanta(TM) (bovine-derived) and InfaSurf(TM) (calf-derived, being developed by Forest Laboratories). In addition, the Company believes that synthetic surfactants will be far less expensive to produce and will not have the viral/prion (suspected to cause "Mad Cow Disease") contamination and immunogenicity concerns associated with animal- derived proteins. The Company further believes that a lower cost of production may make the use of lung surfactants economically feasible for adult indications such as ARDS.

TARGET DISEASE INDICATIONS

The Company intends to initially develop the KL4-Surfactant technology for the treatment of MAS and ARDS. The Company may also develop the KL4-Surfactant technology for the treatment of IRDS.

MECONIUM ASPIRATION SYNDROME.

MAS affects approximately 26,000 newborn infants per year in the United States alone. The disease results from the release of meconium, a greenish, pasty constituent of the fetal bowel, into the amniotic fluid. Meconium is then aspirated into the fetal lungs. The presence of meconium in the infant's lung after delivery often leads to pneumonitis, a generalized inflammation of the lungs, which can result in death. This inflammation degrades lung surfactant and results in insufficient pulmonary function. Presently, there are no products specifically approved for this condition. Treatment consists of general supportive care. Approximately one-third of the infants with MAS require extra-corporeal membrane oxygenation therapy ("ECMO").

ADULT RESPIRATORY DISTRESS SYNDROME.

25

ARDS is a generalized inflammatory disease of the lungs marked by intense leukocytic infiltration, edema and atelectasis (partial lung collapse). Endogenous surfactant in the lung is degraded from this inflammatory cascade leading to further loss of the epithelial cells that make surfactant. The initiating factors of ARDS are numerous and include sepsis, head injury, aspiration of gastric contents and other noxious fluids, trauma, smoke inhalation and broken bones. Patients typically require mechanical ventilation and are at risk of developing multiple organ failure. Mortality has remained at approximately 50%. There is no FDA-approved therapy outside of general supportive care. The incidence is approximately 150,000 patients per year in the United States.

INFANT RESPIRATORY DISTRESS SYNDROME.

IRDS is primarily a disease of premature infants. These infants are born prior to the synthesis of adequate amounts of pulmonary surfactant proteins. The disease affects 40,000 to 50,000 infants per year in the United States and an equal number in Europe. Twenty to forty percent of infants with IRDS develop debilitating bronchopulmonary dysplasia requiring extended ventilatory support and hospitalization. The cost of caring for these infants can exceed $100,000 per patient. Therapy shortly after birth with animal-derived surfactants has proven to be effective in liberating infants from mechanical ventilation or abbreviating the period of ventilation. Surfactant therapy has reduced the historical mortality rate by more than a half to about 10%.

COMPETITIVE ASSESSMENT

Presently, there are no approved drugs that are specifically indicated for MAS or ARDS. Current therapy consists of general supportive care and mechanical ventilation. Three products are specifically approved for the treatment of IRDS. Exosurf(TM), which contains only phospholipids and synthetic organic detergents and no stabilizing protein or peptides, is marketed by Glaxo Wellcome. Survanta(TM), which has been shown to be more effective than Exosurf(TM) in clinical trials, is an extract of bovine lung that contains the cow version of Surfactant Protein B. Survanta(TM) is marketed by Ross Laboratories, a division of Abbott Laboratories, a had estimated 1995 annual sales of approximately $60 million. Recently, Forest Laboratories obtained an approvable letter from the FDA for its calf lung surfactant, Infasurf, for use in IRDS. Although none of the three approved surfactants for IRDS is approved for ARDS, which is a significantly larger market, there are a significant number of other potential therapies in development for the treatment of ARDS that are not surfactant related. Any of these various drugs or devices could significantly impact the commercial opportunity for KL4-Surfactant.

DEVELOPMENT STATUS

INFANT RESPIRATORY DISTRESS SYNDROME

In July 1992, an IND was submitted to the FDA by Charles G. Cochrane, M.D., of Scripps, the inventor of KL4-Surfactant and a consultant to ATI. The IND sought to evaluate the safety and efficacy of KL4-Surfactant in the treatment of IRDS. A total of 47 infants with IRDS were treated with KL4-Surfactant in this multi-center, Phase II clinical trial. The pulmonary function of the infants, measured as a ratio (a/A) of arterial oxygen concentration (a) as a function of the concentration of the inspired oxygen (A), averaged 0.14 (severe respiratory distress) and rose to the normal range (>0.40) within 12 hours of treatment. Airway pressures were reduced over this period and the infants were removed from supportive mechanical ventilation in a mean time of five days. There were no IRDS-related deaths in the trial.

ADULT RESPIRATORY DISTRESS SYNDROME

Dr. Cochrane and his colleagues at Scripps have developed an adult animal model of ARDS. In every case with this model, KL4-Surfactant treatment appeared to re-expand the lungs and induce an elevation of arterial oxygen partial pressure from <100 mmHg to > 400 mmHg within two hours. These experimental results suggest that KL4-Surfactant has the potential to treat patients with this life-threatening condition. In addition, pilot clinical studies on ARDS patients conducted by researchers unaffiliated with the Company or its scientific founders using animal-derived sufactants demonstrated safety and efficacy. Scientists at Justus-Liebig University in Germany conducted a clinical study and concluded that the bronchoscopic application

26

of a high dose of surfactant, aimed at overcoming inhibitory factors in the alveolar space of the patients, may offer a feasible and safe approach to improving gas exchange in severe ARDS patients. The results of this study were published during 1996 in the American Journal of Critical Care Medicine.

MECONIUM ASPIRATION SYNDROME

Dr. Cochrane and his colleagues at Scripps have developed a potential method of preventing MAS by lavaging meconium-filled lungs with diluted KL4-Surfactant. In the lungs of adult rabbits and newborn rhesus monkeys, the lavage not only removed much of the meconium, but it also immediately expanded the lungs and allowed for greater respiration within minutes. The results of these experimental studies suggest that prophylactic KL4-Surfactant administration has the potential to eliminate MAS in newborn infants at risk of developing this life-threatening condition.

INVESTMENT IN ACUTE THERAPEUTICS, INC.; LICENSE OF KL4-SURFACTANT TECHNOLOGY

On October 28, 1996, Discovery completed a transaction pursuant to which it invested $7.5 million in a new majority-owned subsidiary, ATI, in exchange for 600,000 shares of Series A Convertible Preferred Stock of ATI, representing 75% of the outstanding voting securities of ATI following such transaction. Concurrent with Discovery's investment in ATI, J&J, Ortho and ATI entered into an agreement (the "J&J License Agreement") granting an exclusive sublicense of the KL4-Surfactant technology to ATI in exchange for certain license fees, royalties and 40,000 shares of Common Stock of ATI, representing approximately 5% of the outstanding voting securities of ATI. J&J contributed its existing KL4-Surfactant raw material inventory and specialized manufacturing equipment, with an estimated original cost of $3.3 million, to ATI in exchange for shares of nonvoting Series B Preferred Stock of ATI having a $2.2 million liquidation preference. In exchange for its consent to the J&J License Agreement, Scripps received shares of Common Stock of ATI comprising approximately 5% of the outstanding voting securities of ATI.

Pursuant to agreements entered into by the founding management of ATI, members of founding management were granted options to purchase an aggregate of 84,800 shares of Common Stock of ATI. Each founder was granted two options: a Restricted Option and a Basic Option (each as defined below). The "Restricted Options" cover an aggregate of 44,800 shares of Common Stock of ATI, at an exercise price of $0.01 per share, and will be exercisable on the fifth anniversary of the date of grant (or earlier upon the occurrence of an Acceleration Event as defined below). An "Acceleration Event" includes any equity financing of ATI, certain debt financings, or a merger or sale of substantially all of the assets of ATI. If an Acceleration Event occurs prior to the fifth anniversary of the grant date, the Restricted Options will be exercisable based on the valuation of ATI in the Acceleration Event, as set forth below:

   Valuation of ATI Following,                     Percentage of Total
or Consideration Received in, the                   Restricted Option
      Acceleration Event                           Shares Accelerated

     Less than $65 million                                  0%
         Over $65 million                                  25%
         Over $75 million                                  50%
         Over $85 million                                  75%
         Over $95 million                                 100%

The "Basic Options" cover an aggregate of 40,000 shares of Common Stock of ATI at an exercise price of $0.32 per share, and will become exercisable in full upon the expiration of six months following the date of grant. However, in the event that a founder's service terminates prior to the six month anniversary by reason of death, permanent disability or termination for cause, the founder's option shall accelerate and become exercisable as of the date of such termination event.

27

In connection with Discovery's investment in ATI, all of the shareholders of ATI entered into a Co-Sale Agreement. Under the terms of the Co-Sale Agreement, if a shareholder of ATI proposes to sell any shares of stock of ATI (with certain exceptions), each other shareholder has the right to participate PRO RATA in such sale. The Co- Sale Agreement terminates upon the consummation of an underwritten public offering of Common Stock of ATI, an acquisition of ATI or certain insolvency proceedings.

DEVELOPMENT PLAN/SPONSORED RESEARCH AGREEMENT

ATI currently has an approved IND for ARDS. ATI intends to seek FDA approval to amend the approved IND and to re-initiate Phase II clinical trials of KL4-Surfactant for the treatment of ARDS in 1997. ATI has amended its existing IRDS IND to permit the initiation of Phase II clinical trials in MAS. ATI met with the FDA on March 10, 1997, to discuss its MAS development program. ATI received constructive feedback from the FDA and intends to commence its MAS development program on schedule. The Company has not had any discussions with the FDA regarding clinical trials of KL4-Surfactant for the treatment of ARDS, however, and there can be no assurance that approval to amend the ARDS IND will be granted. Orphan drug status for MAS, ARDS and IRDS has been granted by the FDA.

ATI and Scripps have entered into a sponsored research agreement (the "Sponsored Research Agreement") supporting continuing research by Charles G. Cochrane, M.D., and Susan Revak of Scripps. Pursuant to the Sponsored Research Agreement, ATI will contribute $460,000 annually to Scripps' KL4-Surfactant research efforts for an initial two-year period. ATI has an option to acquire an exclusive worldwide license to make, have made, sell or use technology developed under the agreement, which it is required to exercise within 180 days from receipt of notice from Scripps of the development of such technology. Scripps will own all technology that it develops pursuant to work performed under the proposed Sponsored Research Agreement. ATI has the right to receive 50% of the net royalty income received by Scripps for inventions jointly developed by ATI and Scripps to the extent ATI does not exercise its option with respect to such inventions.

ATI has entered into consulting agreements with certain key research personnel at Scripps. See "Executive Compensation and Employment and Consulting Agreements."

ST-630

BACKGROUND

ST-630 is an analog of the active circulating vitamin D hormone calcitriol modified to increase its potency and lengthen its circulating half-life. As a class, vitamin D analogs are commonly used therapies in Europe and Japan for osteoporosis. In aggregate, this class of compounds is believed to generate about $750 million in worldwide sales for osteoporosis. Published studies have confirmed the efficacy of vitamin D analogs in increasing bone mass and decreasing fractures. Vitamin D analogs, however, have not been well accepted in the United States due to certain side effects in the compounds currently marketed. Specifically, prior studies of vitamin D analogs have been associated with hypercalcemia in a percentage of patients. Hypercalcemia is elevated calcium levels in the blood above a generally accepted range. The Company believes that this risk of hypercalcemia may be the primary reason why active vitamin D analogs have only been tested on a limited basis in the United States, which is generally considered to be a high calcium consumption country. No vitamin D analogs are currently marketed for osteoporosis in the United States. Because the Company has not completed a Phase I clinical study of ST-630, the Company has not yet determined whether ST-630 represents a risk of hypercalcemia at any dosage levels that may prove efficacious for treating postmenopausal osteoporosis.

The Company has a license agreement (the "WARF License Agreement") with the Wisconsin Alumni Research Foundation ("WARF") relating to ST-630 and its use in treating postmenopausal osteoporosis. The Company believes that ST-630 may have an improved pharmacological profile compared to earlier, active vitamin D analogs, although there can be no assurance of this. Sumitomo Pharmaceuticals ("Sumitomo") and Taisho Pharmaceuticals ("Taisho") have jointly licensed the right to develop, manufacture and market ST-630 in Japan for the treatment of osteoporosis and are presently conducting the equivalent of a Phase II clinical study of this drug in Japan. The Company has access to the preclinical data generated by Sumitomo and Taisho pursuant to the terms of the WARF License Agreement. The Company intends to seek FDA approval to initiate a Phase I clinical study of ST-630 as a once-daily, orally administered drug for the treatment of osteoporosis in the

28

United States. The Company has not had any discussions with the FDA regarding ST-630, however, and there can be no assurance that such approval will be granted. The Company believes that ST-630 could be administered in combination with other approved drugs for osteoporosis. The composition of matter patent covering ST-630 expires in 2001. A patent covering the use of ST-630 to treat postmenopausal osteoporosis recently issued in the United States. See "Patents, Licenses and Proprietary Rights."

POSTMENOPAUSAL OSTEOPOROSIS

Postmenopausal osteoporosis is a disease of postmenopausal women characterized by decreased bone mass which leads to reduced bone strength and an increased risk of fractures. Typically, fractures occur in the weight-bearing bones of the vertebrae and the hip. On average, women have 10% to 25% less bone mass than men at maturity. When menopause occurs, the production of estrogen diminishes and women experience accelerated bone loss. In the United States, 7 to 20 million women are at risk for developing postmenopausal osteoporosis. In the context of other diseases, a woman's risk of developing a hip fracture is equal to her combined risk of developing breast, uterine and ovarian cancer. One out of every five persons who has a hip fracture will not survive more than one year. In addition, one-third of all patients with hip fractures will become totally dependent and one-half will need assistance with walking. The annual cost of acute care associated with osteoporosis in the United States is estimated to be in excess of $10 billion.

APPROVED THERAPIES FOR OSTEOPOROSIS

ESTROGEN

Estrogen is of proven benefit in treating osteoporosis in postmenopausal women. However, it is associated with significant adverse effects which limit its use for osteoporosis. Estrogen replacement therapy for postmenopausal women can cause hot flashes, menstruation (when taken with progesterone) and, more seriously, may increase the risk of breast and uterine cancer. Extensive use of Vitamin D analogs in Europe and Japan has not revealed any association of Vitamin D analogs with any of these significant adverse side effects. Estrogen must be continually taken or the accumulated bone mass is quickly lost.

FOSAMAX(TM)

Fosamax(TM) or alendronate, from Merck, is the first approved osteoporosis drug in the United States of the bisphosphonate class. (Bisphosphonates are inhibitors of bone resorption mediated by a class of cells called osteoclasts.) The drug is incorporated into bone and prevents calcium in bone from being reabsorbed. While clinical studies have demonstrated increases in bone mass leading to decreased hip and vertebral fractures when the drug is taken for three years, the long-term safety questions of the drug, which is believed to remain in the body for up to a decade are unknown. Many other bisphosphonates are in late-stage clinical testing for osteoporosis. Fosamax(TM) has also been associated with acute esophagitis in some patients. To limit the risk of developing this painful and dangerous condition, patients must take the pill upon awakening in the morning with a full glass of water, remain in a standing position, avoid food for at least half an hour and then consume a full breakfast. Vitamin D analogs have not been associated with acute esophagitis.

NASAL CALCITONIN

Miacalcin(TM) as sold by Sandoz Pharmaceuticals is a nasally administered calcitonin. While the injectable form of calcitonin has proven to be safe and effective for reducing bone pain associated with vertebral fractures, the amount of increase in bone mass is relatively modest. Miacalcin(TM) has never been shown to decrease the risk of fractures.

VITAMIN D AND CALCIUM SUPPLEMENTATION

Currently, vitamin D and calcium supplementation is being studied in a 45,000 patient Women's Health Initiative open label study. Given earlier, smaller studies which have been completed, the Company believes that this study will most likely confirm a modest benefit to increasing bone mass when administered to younger women. Older women and men will probably not

29

benefit from this therapy as it is thought that the kidney's ability to convert vitamin D to the active form is compromised with age.

THERAPIES IN DEVELOPMENT FOR OSTEOPOROSIS

SLOW-RELEASE SODIUM FLUORIDE

Slow-release sodium fluoride is being developed by Mission Pharmacal. In a small study, women on this compound increased bone in their hip and spine and had fewer fractures. However, high doses of sodium fluoride, which had been previously studied in a non slow-release formulation, caused peptic ulcers and built brittle bone. Vitamin D analogs are not known to cause any of these side effects. It is thought that patients taking sodium fluoride will need to be monitored to ensure that their blood fluoride levels stay below toxic levels.

SMALL MOLECULE ESTROGEN AGONISTS/ANTAGONISTS

Raloxifene (being developed by Eli Lilly) and droloxifene (being developed by Pfizer) are small molecule estrogen agonists\antagonists which may offer estrogen's therapeutic benefit to bone without increasing the risk of breast and uterine cancer. The efficacy and adverse effect profile of these compounds in comparison to estrogen are still being studied in late stage clinical trials.

DEVELOPMENT PLAN

The Company has access for regulatory purposes to preclinical data already generated by Sumitomo and Taisho with respect to ST-630 pursuant to the terms of the WARF License Agreement. See "Business--Products and Technologies Under Development--Vitamin D Analog for Treatment of Osteoporosis--ST-630." The Company intends to seek FDA approval to initiate clinical studies of ST-630 as a once-daily, orally administered drug for the treatment of postmenopausal osteoporosis in the United States. Following FDA clearance, if given, the Company intends to conduct an initial dose-ranging study of ST-630 in humans. Based upon the results of the dose-ranging study, the Company may then either seek to further optimize the delivery of ST-630 by testing one or more alternative means of delivery or, assuming acceptable results, seek to initiate a large-scale clinical trial in the United States with effect on bone mineral density being the primary endpoint. The Company has had no interaction with the FDA to date regarding ST-630 and there can be no assurance that the Company's planned clinical trial of ST-630 will receive the requisite regulatory approvals.

GOVERNMENT REGULATION; ORPHAN DRUG DESIGNATION

The testing, manufacture, distribution, advertising and marketing of drug products are subject to extensive regulation by governmental authorities in the United States and other countries. Prior to marketing, any pharmaceutical products developed or licensed by the Company must undergo an extensive regulatory approval process required by the FDA and by comparable agencies in other countries. This process, which includes preclinical studies and clinical trials of each pharmaceutical compound to establish its safety and efficacy and confirmation by the FDA that good laboratory, clinical and manufacturing practices were maintained during testing and manufacturing, can take many years, requires the expenditure of substantial resources and gives larger companies with greater financial resources a competitive advantage over the Company. The FDA review process can be lengthy and unpredictable, and the Company may encounter delays or rejections of its applications when submitted. If questions arise during the FDA review process, approval may take a significantly longer period of time. Generally, in order to gain FDA approval, a company first must conduct preclinical studies in a laboratory and in animal models to obtain preliminary information on a compound's efficacy and to identify any safety problems. The results of these studies are submitted as part of an IND application that the FDA must review before human clinical trials of an investigational drug can start.

Clinical trials are normally done in three phases and generally take two to five years or longer to complete. Typically, clinical testing involves a three-phase process. Phase I consists of testing the drug product in a small number of humans to determine preliminary safety and tolerable dose range. Phase II involves larger studies to evaluate the effectiveness of the drug product in humans having the disease or medical condition for which the product is indicated

30

and to identify possible common adverse effects in a larger group of subjects. Phase III consists of additional controlled testing to establish clinical safety and effectiveness in an expanded patient population of geographically dispersed test sites, to evaluate the overall benefit-risk relationship for administering the product and to provide an adequate basis for product labeling.

After completion of clinical trials of a new drug product, FDA and foreign regulatory authority marketing approval must be obtained. NDAs submitted to the FDA generally take one to three years to obtain approval. If questions arise during the FDA review process, approval may take a significantly longer period of time. The testing and approval processes require substantial time and effort and there can be no assurance that any approval will be granted on a timely basis, if at all. Even if regulatory clearances are obtained, a marketed product is subject to continual review, and later discovery of previously unknown problems or failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. For marketing outside the United States, the Company also will be subject to foreign regulatory requirements governing human clinical trials and marketing approval for pharmaceutical products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. None of the Company's products under development have been approved for marketing in the United States or elsewhere. No assurance can be given that the Company will be able to obtain regulatory approval for any such products under development. Failure to obtain requisite governmental approvals or failure to obtain approvals of the scope requested will delay or preclude the Company or its licensees or marketing partners from marketing their products, or limit the commercial use of the products, and thereby could have a material adverse effect on the Company's business, financial condition and results of operations. See "Risk Factors--Extensive Government Regulation; Uncertainty of FDA and Other Governmental Approval of Products Under Development."

In March 1995, the Company's scientific founders obtained from the FDA an orphan drug designation for the use of tyloxapol to treat CF. In addition, orphan drug status for the use of KL4-Surfactant to treat MAS, ARDS and IRDS has been granted by the FDA. Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs intended to treat a "rare disease or condition," which generally is defined as a disease or condition that affects populations of fewer than 200,000 individuals in the United States. If the Company is the first sponsor to receive FDA approval to market tyloxapol to treat CF, or to market KL4-Surfactant to treat MAS, ARDS or IRDS, the orphan drug designation will, under current law, entitle the Company to a seven-year period of marketing exclusivity in the United States during which the FDA, subject to certain limitations, will not approve another application for the same drug for the same indication. There can be no assurance that the Company will ever receive FDA approval to market SuperVent(TM) to treat CF or to market KL4-Surfactant to treat MAS, ARDS or IRDS, and thus there can be no assurance that the Company will obtain the benefits of any of the aforementioned orphan drug designations. While orphan drug designation and marketing approval may be advantageous to the Company, if achieved, there can be no assurance that the scope of protection or the level of exclusivity that is currently afforded by such designation and approval will remain in effect in the future. In addition, competitors of the Company may obtain orphan drug designation for product candidates that are not the same as SuperVent(TM) or KL4-Surfactant though they are intended to treat the same indications. The Company may request orphan drug designation, if applicable, for more of its products or additional indications as part of its overall regulatory strategy in the future.

PATENTS, LICENSES AND PROPRIETARY RIGHTS

The Company's success will depend in part on patent and trade secret protection for its technologies, products and processes, and on its ability to operate without infringing the proprietary rights of other parties both in the United States and in foreign countries. Because of the substantial length of time and expenses associated with bringing new products through development to the marketplace, the pharmaceutical industry places considerable importance on obtaining and maintaining patent and trade secret protection for new technologies, products and processes. The failure to obtain and maintain patent protection could mean that the Company would face increased competition in the United States and in foreign countries.

LICENSING ARRANGEMENTS

CMHA LICENSE AGREEMENT: SUPERVENT(TM)/TYLOXAPOL

31

The Company depends on its license with CMHA (the "CMHA License Agreement") for the core technology relating to its SuperVent(TM) product under development. The CMHA License Agreement grants the Company an exclusive worldwide license (including the right to sublicense) to develop, make and sell products which are covered in whole or in part by a valid claim contained in the two issued United States patents (United States Patent No. 5,474,760 issued December 12, 1995 and United States Patent No. 5,512,270 issued April 30, 1996) and two pending United States patent applications held by CMHA and licensed to the Company under the CMHA License Agreement, and any later-issued United States and any foreign patents based on or issuing from the issued patents and the pending patent applications. The United States patents cover methods of using tyloxapol, the active compound in SuperVent(TM), to treat cystic fibrosis and methods of treating disease caused by oxidant species, such as myocardial infarction, stroke and ARDS. The two pending United States patent applications relate to the use of tyloxapol as an anti-inflammatory and anti-oxidant agent. Two international applications have been filed under the Patent Cooperation Treaty, and certain corresponding foreign national applications are pending. These applications claim, INTER ALIA, the use of tyloxapol to treat cystic fibrosis and the use of tyloxapol as an anti-oxidant and anti-inflammatory agent. CMHA's United States patents expire in 2013. The CMHA License Agreement is terminable by CMHA: (i) on 60 days' prior notice upon the Company's failure to make timely payments, reimbursements or reports, if the failure is not cured by the Company within 60 days, or (ii) on 90 days' prior notice upon any material breach or default by the Company, if the default or breach is not cured by the Company within 90 days. The termination of the CMHA License Agreement, or the failure to obtain and maintain patent protection for the Company's technologies, would have a material adverse effect on the Company's business, financial condition and results of operations.

In consideration of the license granted to the Company by CMHA, the Company (i) has agreed to pay CMHA (a) royalties on net sales by the Company and by any sublicensees of the Company of products covered by the licensed technology, and
(b) a percentage of any sublicense fees or similar amounts (other than research and development payments) paid to the Company by any sublicensees, and (ii) is responsible for the cost of filing and prosecuting patent applications and maintaining issued patents. The CMHA License Agreement will terminate upon the expiration of the last to expire of the licensed patents.

J&J LICENSE AGREEMENT: KL4-SURFACTANT

Pursuant to the J&J License Agreement, ATI has received an exclusive, worldwide license to commercialize KL4-Surfactant and the other licensed technology for the diagnosis, prevention or treatment of disease, including the right to further sublicense such technology. The exclusive license granted to ATI is a sublicense under certain patent rights previously licensed to J&J by Scripps (the "Scripps Patent Rights") and a license under certain other patent rights held by J&J's Ortho division (the "Ortho Patent Rights" and, together with the Scripps Patent Rights, the "KL4 Patent Rights"). In addition to granting an exclusive sublicense to ATI, J&J has transferred its existing KL4-Surfactant raw material inventory and specialized manufacturing equipment to ATI in exchange for Non-Voting Series B Preferred Stock of ATI.

ATI paid a $200,000 license fee to J&J upon execution of the J&J License Agreement. In addition, ATI will pay J&J a royalty on net sales of KL4-Surfactant sold by it or its sublicensees. The J&J License Agreement further provides for the making of milestone payments as follows: $250,000 upon the filing of the first New Drug Application ("NDA") for a product in a neonatal indication; $500,000 upon approval of the first NDA for a product in a neonatal indication; $500,000 upon filing of the first NDA for a product in the ARDS indication; and $1,500,000 upon approval of the first NDA for a product in the ARDS indication. Royalties are payable for a minimum period of ten years from the first commercial sale of a product in each country and, thereafter (if applicable) until expiration of the last to expire of the KL4 Patent Rights in such country, after which time ATI will have a fully paid license.

The Scripps Patent Rights consist of three issued United States patents and two pending United States applications. The three issued patents are United States Patent No. 5,407,914, issued April 18, 1995; U.S. Patent No. 5,260,273, issued November 9, 1993; and U.S. Patent No. 5,164,369, issued November 17, 1992. These patents relate to synthetic pulmonary surfactants (including KL4-Surfactant), certain related polypeptides and a method of treating respiratory distress syndrome with these surfactants. The first of these patents will expire in 2009. The two pending United States applications relate to pulmonary surfactants, related polypeptides, liposomal surfactant compositions and methods of treating respiratory distress syndromes with these surfactants and compositions. Corresponding foreign patent applications are pending in the European Patent Office, certain European countries, Canada and Japan. Two patents have issued in Australia and one patent has issued in Norway. The Company believes that the respiratory distress syndromes covered by these patents and patent applications include MAS,

32

ARDS and IRDS. Scripps is responsible for filing, prosecuting and maintaining the Scripps Patent Rights and J&J is required to reimburse Scripps for the costs of such filings, prosecution and maintenance. The Ortho Patent Rights consist of certain pending United States patent applications which relate to methods of manufacturing certain peptides which may be used in the manufacture of KL4-Surfactant. J&J is responsible for filing, prosecuting and maintaining the Ortho Patent Rights.

WARF LICENSE AGREEMENT: ST-630

Pursuant to the WARF License Agreement, the Company has an exclusive license within all countries in the Western hemisphere, including the right to sublicense, in the field of prevention, treatment, amelioration or cure of bone disease, under U.S. Patent No. 4,358,406 (the "ST-630 Patent") covering the compound ST-630 and U.S. Patent No. 5,571,802 covering a method for treating postmenopausal osteoporosis (the "ST-630 Use Patent"). In addition, the Company has an option to extend the exclusive license to the remaining countries of the world with the exception of Japan. The Company's option expires on January 1, 2002 and, with respect to Argentina, Spain, Portugal and Korea, must be exercised prior to the commencement of product development therein.

The Company paid a one-time fee of $400,000 to WARF upon execution of the WARF License Agreement. The Company is obligated to pay WARF a royalty on net sales of ST-630 sold by it or its sublicensees in the licensed territories. In addition, the Company is obligated to pay WARF a percentage of its income from sublicensees. The WARF License Agreement also provides for the making of the following milestone and option payments:

For the exclusive license to the Western hemisphere: $150,000 upon completion of Phase II studies in the United States; and $1 million upon NDA submission in the United States. For the option for an exclusive license to Belgium, France, Germany, Italy, the Netherlands, Switzerland and the United Kingdom: $200,000 upon exercise of the Company's option and $1 million upon the first submission of an NDA with any European country. For the option for an exclusive license for the remaining countries of the world (other than Argentina, Spain, Portugal, Korea and Japan): $500,000 upon exercise of the Company's option. For the option for an exclusive license for Argentina, $10,000; for Spain, $170,000; for Portugal, $50,000; and for Korea, $15,000, in each case upon exercise of the Company's option. Each such option must be exercised no later than January 1, 2002.

To maintain the license, the Company is required to pay minimum royalties of $100,000 per year beginning in calendar year 2002. The WARF License Agreement shall remain in effect and royalties shall be payable for a period of fifteen years from the date approval is received in the United States for the sale of ST-630, after which time the Company shall have a fully paid license.

So long as the WARF License Agreement remains in effect, WARF is prohibited from granting a license to any other party (other than in Japan) with respect to ST-630 or certain proprietary information relating thereto for any indication, with the exception of WARF's existing license agreement with Penederm, Inc.

The ST-630 Patent will expire in July 2001, which the Company anticipates will be prior to receipt of any marketing approval for ST-630 in the United States . The ST-630 Use Patent, which expires in 2014, is limited to claims relating to a method of treating postmenopausal osteoporosis in humans having such disease with an effective dosage of ST-630. These claims do not include claims relating to the use of ST-630 to treat other metabolic bone disorders, such as age-related osteoporosis (which occurs in men and women) and renal osteodystrophy. At the Company's request, WARF recently filed an application to pursue additional claims relating to the use of ST-630 to treat other metabolic bone diseases. However, there can be no assurance that any patent containing such additional claims will issue in the United States or elsewhere.

Foreign patent applications corresponding to the ST-630 Patent and/or the ST-630 Use Patent have also been filed in certain countries, and such applications and any resulting patents are licensed to the Company under the WARF License Agreement. United States and foreign patents covering certain processes relating to the manufacture of vitamin D analogs, which have been nonexclusively licensed to the Company under the WARF License Agreement, will expire on various dates up to 2005.

UNCERTAINTY OF BIOTECHNOLOGY PATENTS

33

The patent position of firms relying upon biotechnologies is highly uncertain and involves complex legal and factual questions. To date, there has emerged no consistent policy regarding the breadth of claims allowed in biotechnology patents or the degree of protection afforded under such patents. The patent application and issuance process can be expected to take several years and could entail considerable expense to the Company. There can be no assurance that patents will issue as a result of any applications filed or that the existing patents or patents issued from existing applications will be sufficiently broad to afford protection against competitors with similar technology. In addition, there can be no assurance that such patents will not be challenged, invalidated or circumvented, or that the rights granted thereunder will provide competitive advantages to the Company. The commercial success of the Company will also depend upon its avoidance of infringement of patents issued to competitors. A United States patent application is maintained under conditions of confidentiality while the application is pending, so the Company cannot determine the inventions being claimed in pending patent applications filed by third parties. Litigation may be necessary to defend or enforce the Company's patent and license rights or to determine the scope and validity of the proprietary rights of others. Defense and enforcement of patent claims can be expensive and time consuming, even in those instances in which the outcome is favorable to the Company, and can result in the diversion of substantial resources from the Company's other activities. An adverse outcome could subject the Company to significant liabilities to third parties, require the Company to obtain licenses from third parties, or require the Company to alter its products or processes, or cease altogether any related research and development activities or product sales, any of which may have a material adverse effect on the Company's business, financial condition and results of operations.

Tyloxapol, the active compound in SuperVent(TM), was the subject of an issued U.S. composition of matter patent which expired in 1965. The patents and patent applications licensed to the Company differ from the expired patent, inter alia, in that one patent application covers proprietary pharmaceutical formulations containing high concentrations of tyloxapol and the other patents and patent applications cover uses of tyloxapol to treat certain diseases. Although the Company believes that high concentration formulations of tyloxapol will represent the most practical means to deliver the active compound, there can be no assurance that any patent application covering this formulation will issue or that the compound will not prove similarly effective in lower concentrations which are not covered by any of the Company's patent applications.

CONFIDENTIALITY; ASSIGNMENT OF INVENTIONS

The Company requires all employees to enter into confidentiality agreements that prohibit the disclosure of confidential information to third parties and require disclosure and assignment to the Company of rights to their ideas, developments, discoveries and inventions. In addition, the Company seeks to obtain such agreements from its consultants, advisors and research collaborators; however, such agreements may not be possible where such persons are employed by universities or other academic institutions that require assignment of employee inventions to them. To the extent that consultants, key employees, or other third parties apply technological information independently developed by them or by others to any of the proposed projects of the Company, disputes may arise as to the proprietary rights to such information which may not be resolved in favor of the Company. In addition, the Company also relies on trade secrets and proprietary know-how, that it seeks to protect in part by its confidentiality agreements with its employees, consultants, advisors or others. There can be no assurance that these agreements will not be breached, that the Company would obtain adequate remedies for any breach, or that such trade secrets or proprietary know-how will not otherwise become known or be independently developed by competitors in such a manner that the Company has no legal recourse.

THIRD PARTY SUPPLIERS

To be successful, the Company's products must be manufactured in commercial quantities under good manufacturing practice ("GMP") requirements set by the FDA at acceptable costs. The FDA periodically inspects manufacturing facilities in the United States in order to assure compliance with applicable GMP requirements. Foreign manufacturers also are inspected by the FDA if their drugs are marketed in the United States. Failure of the foreign or domestic suppliers of the Company's products or failure of the manufacturers of the Company's products to comply with GMP regulations or other FDA regulatory requirements would have a material adverse effect on the Company's business, financial condition and results of operations. The Company does not have any manufacturing capacity of its own but instead intends to rely on outside manufacturers to produce appropriate clinical grade material for its use in clinical studies for certain of its products.

34

The active compound in SuperVent(TM) is presently manufactured for several third parties pursuant to GMP standards by an affiliate of Sanofi-Winthrop, Inc. ("Sanofi"), a multinational pharmaceutical company. Sanofi is the sole supplier of tyloxapol with GMP standard manufacturing capabilities and there are few alternative non-GMP approved sources of supply. Although Sanofi has sold a quantity of tyloxapol sufficient for the Company's proposed Phase I/II clinical trial of SuperVent(TM), the Company does not presently have an agreement with Sanofi to supply any additional material, either in connection with a Phase III clinical trial or, following regulatory approval, for marketing purposes. In addition, the Company does not intend to enter into an agreement for supply of the formulated drug containing tyloxapol unless it plans to initiate a Phase III clinical trial of tyloxapol for the treatment of CF. There can be no assurance that the Company will be able to enter into a supply agreement with Sanofi or a supplier of the formulated drug on terms acceptable to the Company, if at all. In such case, the Company would be required to seek alternate manufacturing sources capable of producing tyloxapol and the formulated drug. There can be no assurance that the Company will be able to identify and contract with alternative manufacturers on terms acceptable to it, if at all. Any interruption in the supply of tyloxapol would have a material adverse effect on the Company's business, financial condition and results of operations. The Company has entered into an agreement with Cook Imaging Corporation for the packaging and storage, under sterile and stable conditions, of purchased tyloxapol.

The Company is in negotiations with Tetrionics, Inc. ("Tetrionics") to manufacture, formulate and supply the Company with GMP-grade ST-630 for the Company's investigational and commercial purposes. Tetrionics presently manufactures and supplies ST-630 to Penederm Inc. in the United States for investigational topical use for the treatment of psoriasis. There can be no assurance that the Company will be able to reach agreement with this proposed manufacturer on terms acceptable to the Company, if at all. Any failure to achieve agreement may substantially delay the Company's development of ST-630.

MARKETING AND SALES

It is the Company's long-term goal to market SuperVent(TM) for CF and possibly certain of its other products through a direct sales force (or, in the case of CF, possibly through the distribution capabilities of the Cystic Fibrosis Foundation), if and when any necessary regulatory approvals are obtained. The Company currently has no marketing and sales experience and no marketing or sales personnel. Unless a sales force is established, the Company will be dependent on corporate partners or other entities for the marketing and selling of its products. There can be no assurance that the Company will be able to enter into any satisfactory arrangements for the marketing and selling of its products. The inability of the Company to enter into such third party distribution, marketing and selling arrangements for its anticipated products could have a material adverse effect on the Company's business, financial condition and results of operations.

EMPLOYEES

The Company utilizes a product development strategy that involves contracting out research, development and manufacturing functions to third parties in order to minimize the expense and overhead associated with full-time employees. Consistent with this strategy, Discovery has only nine employees. James S. Kuo, M.D., joined Discovery in April 1996 as President, Chief Executive Officer and a Director. David R. Crockford joined Discovery in November 1996 as Vice President of Regulatory Affairs. Saul S. Bodenheimer, M.D., joined Discovery in December 1996 as Vice President of Clinical Affairs.

All directors hold office until the next annual meeting of stockholders of
Discovery or ATI, as the case may be, or until their successors have been
elected and qualified. Officers serve at the discretion of the applicable Board
of Directors. The Bylaws of each of Discovery and ATI provide that directors and
officers shall be indemnified against liabilities arising from their service as
directors or officers to the fullest extent permitted by the laws of the State
of Delaware, which generally requires that the individual act in good faith and
in a manner he or she reasonably believes to be in or not opposed to the best
interests of Discovery or ATI, as the case may be. Insofar as indemnification
for liabilities arising under the Securities Act of 1933


                                       43

(THE "SECURITIES ACT") MAY BE PERMITTED TO DIRECTORS, OFFICERS AND CONTROLLING
PERSONS OF THE COMPANY PURSUANT TO THE FOREGOING PROVISIONS, OR OTHERWISE, THE
COMPANY HAS BEEN ADVISED THAT IN THE OPINION OF THE SECURITIES AND EXCHANGE
COMMISSION SUCH INDEMNIFICATION IS AGAINST PUBLIC POLICY AS EXPRESSED IN THE
SECURITIES ACT AND IS, THEREFORE, UNENFORCEABLE. IN THE EVENT THAT A CLAIM FOR
INDEMNIFICATION AGAINST SUCH LIABILITIES (OTHER THAN THE PAYMENT BY THE COMPANY
OF EXPENSES INCURRED OR PAID BY A DIRECTOR, OFFICER OR CONTROLLING PERSON OF THE
COMPANY IN THE SUCCESSFUL DEFENSE OF ANY ACTION, SUIT OR PROCEEDING) IS ASSERTED
BY SUCH DIRECTOR, OFFICER OR CONTROLLING PERSON IN CONNECTION WITH THE
SECURITIES BEING REGISTERED HEREBY, THE COMPANY WILL, UNLESS IN THE OPINION OF
ITS COUNSEL THE MATTER HAS BEEN SETTLED
BY CONTROLLING PRECEDENT, SUBMIT TO A COURT OF APPROPRIATE JURISDICTION THE
QUESTION WHETHER SUCH INDEMNIFICATION BY IT IS AGAINST PUBLIC POLICY AS
EXPRESSED IN THE SECURITIES ACT AND WILL BE GOVERNED BY THE FINAL ADJUDICATION
OF SUCH ISSUE.

The Company has 17 employees. Two employees, Messrs. Kanzer and Johnson,
currently devote only a portion of their time to the Company. Certain of the
officers and directors of the Company currently do and may from time to time in
the future serve as officers or directors of other biopharmaceutical or
biotechnical companies. There can be no assurance that such other companies will
not in the future have interests in conflict with those of the Company. See
"Risk Factors--No Assurance of Additional Products; Risks Associated with
Products in Development" and "--Certain Interlocking Relationships; Potential
Conflicts of Interest."

DISCOVERY OPTION PLAN

Discovery has adopted the 1996 Stock Option/Stock Issuance Plan consisting of a
Discretionary Option Grant Program for employees, a Stock Issuance Program for
employees and an Automatic Option Grant Program under which option grants will
automatically be made at periodic intervals to eligible non-employee directors
to purchase shares of Common Stock. The exercise price under options issued
pursuant to the Discretionary Option Grant Program and the Automatic Option
Grant Program shall equal at least 85% of the fair market value of the Common
Stock on the grant date (and, in the case of incentive stock options, 100%).
Under the Discretionary Option Grant Program, options will be granted to
employees either as incentive stock options or non-statutory options and will
vest over a specified period of time (generally three to five years) as
determined by the Discovery Board of Directors. Discovery has reserved 1,125,000
shares for issuance under these plans.

Under the Stock Issuance Program, shares of Common Stock may be issued directly
without any intervening option grant in consideration for cash or past services
rendered to Discovery (or any parent or subsidiary of Discovery). Shares of
Common Stock issued under the Stock Issuance program may vest immediately or may
vest in one or more installments or upon the recipient's attainment of specified
performance objectives. Unvested shares held by the grantee may be canceled (or,
if issued for cash, repurchased at their original purchase price) in the event
the recipient ceases to remain in the service of Discovery or fails to attain
specified performance objectives.

Under the Automatic Option Grant Program, each non-employee director of
Discovery will automatically be granted an option for 25,000 shares of Common
Stock on the date of his or her election or appointment to the Board of
Directors, and each eligible non-employee director who is to continue to serve
as a director shall be granted an option to purchase an additional 10,000 shares
of Common Stock on the date of each annual meeting of stockholders (provided
such eligible non-employee director has served for at least 6 months). Such
options shall vest over four years. Each option will have a term of ten years,
subject to earlier termination following the optionee's cessation of service
on the Board of Directors. Each option will be immediately exercisable; however,
any shares purchased upon exercise of the option will be subject to repurchase
should the optionee's service as a non-employee director cease prior to vesting
of the shares.

Should Discovery be acquired by merger or asset sale or should there occur a
hostile change in control or ownership of Discovery, each outstanding stock
option will immediately vest in full either at the time of such acquisition or
hostile take-over (subject to certain exceptions) or upon the subsequent
termination of the individual's service with Discovery.

should the optionee's service as a non-employee director cease prior to vesting
of the shares. Each automatic share grant will vest in successive equal annual
installments over a three-year period.

time to time on an informal basis. The Company anticipates that MAB and SAB
members will review and provide advice to management on clinical trial design,
scientific planning and research and development. The Company expects that in
the future it will compensate certain of its medical advisors on a per-meeting
basis and/or through the granting of stock options.

MAB and SAB members may be employed by or have consulting agreements with
entities other than the Company, some of which may conflict or compete with the
Company, or which may limit a particular member's availability to the Company.
Certain of the institutions with which MAB and SAB members are affiliated may
have regulations or policies which are unclear with respect to the ability of
such personnel to act as part-time consultants or in other capacities for a
commercial enterprise. Regulations or policies now in effect or adopted in the
future might limit the ability of MAB and SAB members to consult with the
Company. The loss of the services of MAB or SAB members could have a material
adverse effect on the Company.

Although each current MAB and SAB member has the customary contractual
obligation to keep confidential and not to disclose nor use any confidential or
proprietary information of the Company, inventions or processes discovered by
any MAB or SAB member, unless otherwise agreed, will not become the property of
the Company but will remain the property of such



                                       49

person or of such person's full-time employers. In addition, the institutions
with which the MAB and SAB members are affiliated may make available the
research services of their scientific and other skilled personnel, including the
MAB and SAB members to entities other than the Company. In rendering such
services, such institutions may be obligated to assign or license to a
competitor of the Company patents and other proprietary information which may
result from such services, including research performed by an advisor or
consultant for a competitor of the Company.

                              CERTAIN TRANSACTIONS

Pursuant to a private offering held during June through November 1996, the
Company consummated an offering of Units consisting of Series A Preferred Stock
and Common Stock (the "Unit Offering") pursuant to which the Company raised
aggregate gross proceeds of approximately $22,002,550. In connection with
services rendered by Paramount as placement agent for the Unit Offering, and
pursuant to a placement agency agreement entered into by the Company and
Paramount, the Company paid Paramount cash commissions of approximately
$1,980,230, a non-accountable expense allowance of approximately $880,102 and
placement warrants to acquire 220,026 shares of Series A Preferred Stock,
exercisable until November 8, 2006 at an exercise price of $11 per share of
Series A Preferred Stock and 220,026 shares of Common Stock, exercisable until
November 8, 2006 at an exercise price of $0.25 per share. See "Description of
Securities--Placement Agent Warrants."

Pursuant to such placement agency agreement, on November 7, 1996, the Company
and Paramount entered into a Financial Advisory Agreement, pursuant to which
Paramount will act as the Company's financial advisor. Such engagement provides
that Paramount will receive a monthly retainer of $4,000 per month for a minimum
of 24 months, plus expenses and success fees.

The Company has agreed to indemnify Paramount and certain related parties with
respect to liabilities arising out of the Unit Offering under the Federal
securities laws pursuant to the Placement Agency Agreement entered into by the
Company and Paramount. The Company has also agreed to indemnify Paramount and
certain related parties with respect to liabilities arising out of services
rendered pursuant to the Financial Advisory Agreement.

Steve H. Kanzer, C.P.A., ESQ., the Chairman of the Board of Directors and a

Common Stock to RAQ, LLC for $0.002 per share. Dr. Rosenwald is the Chief
Executive Officer of RAQ, LLC. During 1995 and the first quarter of 1996, Dr.
Rosenwald provided loans to the Company in the aggregate amount of $17,794, the
proceeds of which were used for salary and administrative purposes. Dr.
Rosenwald contributed such loans to the capital of the Company prior to the
initiation of the Unit Offering. Dr. Rosenwald had guaranteed a credit facility
provided by Fleet Bank in favor of the Company in an amount up to $350,000. The
proceeds of these loans were used by the Company in connection with its entry
into the CMHA License Agreement and for general operating and working capital
purposes. The outstanding balance of such loans, $201,000, was repaid in
September 1996 using a portion of the proceeds of the Unit Offering.

                                       52

                            DESCRIPTION OF SECURITIES

The Company is authorized to issue up to 50,000,000 shares of Common Stock, par
value $0.001 per share, and 10,000,000 shares of Preferred Stock, par value,
$0.001 per share. As of January 2, 1997, 6,712,256 shares of Common Stock and
2,200,256 shares of Series A Preferred Stock were issued and outstanding.

COMMON STOCK

Each holder of Common Stock is entitled to one vote for each share held of
record. There is no right to cumulative voting of shares for the election of
Directors. The shares of Common Stock are not entitled to preemptive rights and
are not subject to redemption or assessment. Subject to the rights of holders of
Preferred Stock of the Company, each share of Common Stock is entitled to share
ratably in distributions to stockholders and to receive ratably such dividends
as may be declared by the Board of Directors out of funds legally available
therefor. Subject to the rights of holders of Preferred Stock of the Company,
upon liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to receive, pro-rata, the assets of the Company which
are legally available for distribution to stockholders. The issued and
outstanding shares of Common Stock are validly issued, fully paid and
non-assessable.

PREFERRED STOCK

The preferred stock of the Company can be issued in one or more series as may be
determined from time-to-time by the Board of Directors. In establishing a
series, the Board of Directors shall give to it a distinctive designation so as
to distinguish it from the shares of all other series and classes, and shall fix
the number of shares in such series and the preferences, rights and restrictions
thereof. All shares of any one series shall be alike in every particular. The
Board of Directors has the authority, without stockholder approval, to fix the
rights, preferences, privileges and restrictions of any series of preferred
stock including, without limitation: (a) the rate of distribution; (b) the price
at which and the terms and conditions on which shares shall be redeemed; (c) the
amount payable upon shares for distributions of any kind; (d) sinking fund
provisions for the redemption of shares; (e) the terms and conditions on which
shares may be converted if the shares of any series are issued with the
privilege of conversion; and (f) voting rights except as limited by law.

Although the Company currently does not have any fixed plans to designate any
series of preferred stock other than the Series A Preferred Stock or to issue
additional shares of preferred stock other than the shares of Series A Preferred
Stock issuable upon exercise of the Preferred Placement Warrants, there can be
no assurance that the Company will not do so in the future. As a result, the
Company could authorize the issuance of a series of preferred stock which would
grant to holders preferred rights to the assets of the Company upon liquidation,
the right to receive dividend coupons before dividends would be declared to
holders of Common Stock, and the right to the redemption of such shares,
together with a premium, prior to the redemption of Common Stock. The current
stockholders of the Company have no redemption rights. In addition, the Board of
Directors could issue large blocks of voting stock to fend off unwanted tender
offers or hostile takeovers without further stockholder approval.

SERIES A PREFERRED STOCK

The following is a brief summary of certain provisions of the Series A Preferred
Stock, but this summary does not purport to be complete and is qualified in all
respects by reference to the actual text of the Certificate of Designations for
the Series A Preferred Stock, a copy of which has been included as an Exhibit to
the Registration Statement and is incorporated herein by reference.

The Board of Directors of the Company has authorized the issuance of up to
7,000,000 shares of Series A Preferred Stock, the rights, preferences and
characteristics of which are as follows:

    DIVIDENDS

The holders of Series A Preferred Stock will be entitled to receive dividends
if, as and when declared by the Board of Directors of the Company out of funds
legally available therefor. No dividend or distribution, as the case may be,
will be declared or paid on any junior stock (including the Common Stock) unless
the dividend also is paid to holders of the Series A Preferred Stock. The
Company does not intend to pay cash dividends on the Series A Preferred Stock or
the underlying Common Stock for the foreseeable future.


                                       53

    CONVERSION

Each share of Series A Preferred Stock may be converted, in whole or in part, at
the option of the holder at any time after the initial issuance date into four
shares of Common Stock based upon an initial conversion price equal to $2.50 per
share of Common Stock (the "Preferred Conversion Price"). The Preferred
Conversion Price is subject to adjustment upon the occurrence of certain
mergers, reorganizations, consolidations, reclassifications, stock dividends or
stock splits that will result in an increase or decrease in the number of shares
of Common Stock outstanding. In addition, the Preferred Conversion Price is
subject to adjustment on the date which is 12 months after the first date on
which shares of the capital stock (or securities received in exchange for the
capital stock) are traded on a national securities exchange for the capital
stock, or are quoted on the National Association of Securities Dealers Automated
Quotation System, the OTC Electronic Bulletin Board or the "Pink Sheets," (the
"Reset Date") if the average closing bid trading price of the Common Stock for
the 30 consecutive trading days immediately preceding the Reset Date (the
"Twelve Month Trading Price") is less than 135% of the then applicable Preferred
Conversion Price ("Reset Event"). Upon the occurrence of a Reset Event, the then
applicable Preferred Conversion Price will be reduced to equal the greater of
(i) the Twelve Month Trading Price divided by 1.35 and (ii) 50% of the then
applicable Preferred Conversion Price.

    MANDATORY CONVERSION

The Company has the right at any time after the Reset Date to cause the Series A
Preferred Stock to be converted in whole or in part, on a PRO RATA basis, into
shares of Common Stock at the applicable Preferred Conversion Price if the
closing price of the Common Stock exceeds 150% of the then applicable Preferred
Conversion Price for at least 20 trading days in any 30 consecutive trading day
period.

    LIQUIDATION PREFERENCE

Upon a (i) liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, (ii) sale or other disposition of all or substantially
all of the assets of the Company or (iii) merger or consolidation in which the
Company is not the surviving entity and voting power of the Company's
stockholders after such transaction is less than 50% (a "Merger Transaction")
((i), (ii) and (iii) being collectively referred to as a "Liquidation Event"),
after payment or provision for payment of the debts and other liabilities of the
Company, the holders of the Series A Preferred Stock then outstanding will first
be entitled to receive, PRO RATA, and in preference to the holders of the Common
Stock and any other series of Preferred Stock of the Company, an amount per
share equal to $13.50, subject to adjustment, plus accrued but unpaid dividends,
if any; PROVIDED, HOWEVER, that in the case of a Merger Transaction, such $13.50
per share may be paid in cash and/or securities of the surviving entity in such
Merger Transaction.

    VOTING RIGHTS

The holders of the Series A Preferred Stock have the right at all meetings of
stockholders to the number of votes equal to the number of shares of Common
Stock issuable upon conversion of the Series A Preferred Stock at the record
date for determination of the stockholders entitled to vote. So long as a
majority of the shares of Series A Preferred Stock remain outstanding, the
holders of 66.67% of the Series A Preferred Stock are required to approve (i)
the issuance of any securities of the Company senior to or on parity with the
Series A Preferred Stock, (ii) any material alteration or change in the rights
or preferences or privileges of the Series A Preferred Stock and (iii) the
declaration or payment of any dividend on any junior stock or the repurchase of
any securities of the Company. Except as provided above or as required by
applicable law, the holders of the Series A Preferred Stock, other than in
connection with vesting provisions of employee and consultant agreements, vote
together with the holders of the Common Stock and not as a separate class.

    LOCK-UP AND BLACKOUT PERIODS

The holders of shares of Common Stock issuable upon conversion of shares of
Series A Preferred Stock (the "Conversion Shares") have agreed pursuant to their
subscription agreements with the Company executed in connection with the Unit
Offering not to offer, pledge, sell, contract to sell, grant any option for the
sale of, or otherwise dispose of, directly or indirectly, any Conversion Shares,
without the prior written consent of Paramount. Such restrictions apply until
(i) three months after the first date on which the shares of Common Stock become
publicly traded (the "Initial Trading Date") with respect to 100% of each of the
holders' Conversion Shares, (ii) six months after the Initial Trading Date with
respect to 75% of such Conversion Shares, (iii) nine months after the Initial
Trading Date with respect to 50% of such Conversion Shares, and (iv) 12 months
after the Initial Trading Date with respect to the remaining 25% of such
Conversion Shares.


                                       54

The holders of Series A Preferred Stock issuable upon exercise of the Preferred
Placement Warrants and the Common Stock issuable upon conversion thereof
(collectively, the "Placement Conversion Shares") are bound, pursuant to the
terms of such Preferred Placement Warrants, not to offer, pledge, sell, contract
to sell, grant any option for the sale of, or otherwise dispose of, directly or
indirectly, any of the Placement Conversion Shares prior to 12 months after the
initial trading date of such Placement Conversion Shares.

In addition, any shares of Common Stock issuable upon conversion of the Series A
Preferred Stock shall be subject to a blackout period with respect to the
Registration Statement for the following periods: (i) any period not to exceed
two 30-day periods within any one 12-month period the Company requires in
connection with a primary underwritten offering of equity securities and (ii)
any period, not to exceed a 60-day period per circumstance or development, when
the Company determines in good faith that offers and sales pursuant thereto
should not be made by reason of the presence of material undisclosed
circumstances or developments with respect to which the disclosure that would be
required in such a prospectus is premature, would have a material adverse effect
on the Company or is otherwise inadvisable.

STOCK OPTIONS

A total of 1,250,000 shares of Common Stock has been reserved for issuance
under the Company's 1996 Stock Option Plan (the "Option Plan"). The Option Plan
was adopted by the Board of Directors in October 1996. The Option Plan expires
by its own terms in 2006. See "Management--Discovery Option Plan." Such options
do not confer upon holders thereof any voting or any other rights of a
stockholder of the Company. The shares of Common Stock issuable upon exercise of
the options and warrants in accordance with the terms thereof, will be fully
paid and nonassessable.


Any issuance of stock pursuant to the Stock Option Plan may dilute the value of
the shares of Common Stock.

PLACEMENT AGENT WARRANTS

The following summaries are qualified in their entirety by the text of the
warrants, copies of which have been filed as exhibits to the Registration
Statement.

In connection with services rendered by Paramount, as placement agent in the
Unit Offering, and pursuant to a placement agency agreement entered into by the
Company and Paramount, the Company issued to Paramount and/or its designees
warrants to acquire approximately 220,026 newly issued shares of Series A
Preferred Stock (the "Preferred Placement Warrants"). Each Preferred Placement
Warrant entitles the registered holder thereof to purchase Series A Preferred
Stock at a price of $11 per share, at any time until November 8, 2006. In
connection therewith, the Company also issued to Paramount and/or its designees
warrants to acquire approximately 220,026 newly issued shares of Common Stock
(the "Common Placement Warrants," and collectively with the Preferred Placement
Warrants, the "Placement Agent Warrants"). Each Common Placement Warrant
entitles the registered holder thereof to purchase Common Stock at a price of
$0.25 per share, at any time until November 8, 2006.


The Placement Agent Warrants may be exercised in whole or in part and may be
exercised on a "net exercise" basis pursuant to a provision that does not
require the payment of any cash to the Company. The Common Stock issuable upon
conversion of the Series A Preferred Stock issuable upon exercise of the
Preferred Placement Warrants, and such Series A Preferred Stock, are subject to
certain lock-up restrictions. See "Series A Preferred Stock--Lock-up and
Blackout Periods."


The Placement Agent Warrants contain provisions to protect the holders thereof
against dilution by adjusting the price at which the Placement Agent Warrants
are exercisable and the number of shares issuable upon exercise thereof upon the
occurrence of certain events, including the payment of stock dividends and
distributions, stock splits, recapitalization, reclassifications and
reorganizations affecting the Company's securities and issuances of shares at
below the then market price.


                                       55

The Company is not required to issue fractional shares of common Stock upon
exercise of any such warrants. In lieu thereof, an amount of cash equal to the
same fraction of the then current market value of a share of Common Stock will
be paid. No adjustment as to dividends will be made upon any exercise of any
such warrants. The holder of any such warrant will not have any rights as a
holder of Common Stock unless and until the applicable warrant is exercised for
the Common Stock issuable upon such exercise.

REGISTRATION RIGHTS

Pursuant to an investor rights agreement, RAQ, LLC, the holder of 2,727,600
shares of Common Stock has unlimited "piggyback" registration rights and two
demand Form S-3 registration rights per year subsequent to an initial public
offering of the Common Stock with respect to such shares. These registration
rights are subject to certain conditions and limitations, including a "lock-up"
provision for a period of 12 months following the Initial Trading Date and the
right of the underwriters to restrict the number of shares offered in a
registration.


In March 1996, RAQ, LLC entered into separate Co-Sale and Co-Registration
Agreements with Thomas P. Kennedy, M.D., and John R. Hoidal, M.D., pursuant
to which RAQ, LLC, among other things, agreed not to sell or transfer certain of
its securities of the Company unless Dr. Kennedy or Dr. Hoidal, as applicable,
was given the opportunity to participate in such transaction. RAQ, LLC also
agreed to use its best efforts to grant Dr. Kennedy or Dr. Hoidal, as
applicable, access to such registration rights as RAQ, LLC may have with respect
to securities of the Company.


TRANSFER AGENT

The Transfer Agent for the shares of Common Stock is American Stock Transfer &
Trust Company of New York.

(1) Unless otherwise indicated, includes all shares of Common Stock issuable upon conversion of the Series A Preferred Stock at the initial conversion rate of $2.50 per share. See "Description of Securities--Series A Preferred Stock."

Each Selling Securityholder may, but is not required to, sell all of the shares of Common Stock shown in the column entitled "Amount of Shares to be Offered" subject, in certain instances, to lock-up provisions. See "Description of Securities--Series A Preferred Stock--Lock-Up and Blackout Periods." The Selling Securityholders and any broker-dealers that act in connection with the sale of the Common Stock as principals may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act and any commission received by them and any profit on the resale of such securities as principals might be deemed to be underwriting discounts and commissions under the Act. The Selling Securityholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of such securities certain liabilities, including liabilities arising under the Securities Act. The Company will not receive any proceeds from the sales of the Common Stock by the Selling Securityholders, although the Company may receive proceeds from the exercise of the Placement Agent Warrants. Sales by the Selling Securityholders, or even the potential for such sales, would likely have an adverse effect on the market price of the Common Stock.

At the time a particular offer for Common Stock is made, except as herein contemplated, by or on behalf of the Selling Securityholder, to the extent required, a Prospectus will be distributed by the Selling Securityholder which will set forth the number of shares of Common Stock being offered and the terms of the Offering, including the name or names of any underwriters, dealers or agents, if any, the purchase price paid by any underwriter for shares purchased from the Selling Securityholder and any discounts, commissions or concessions allowed or reallowed or paid to dealers.

Except as noted below, none of the Selling Securityholders named in the preceding table has had any position, office or other material relationship with the Company or any of its affiliates within the past three years. The Aries Domestic Fund, L.P. and The Aries Fund, a Cayman Island Trust are private investment funds managed by ^ Lindsay A. Rosenwald, M.D., the Chief Executive Officer of RAQ, LLC, the controlling stockholder of the Company and the Chairman of the Board of Directors, Chief Executive Officer, President and sole stockholder of Paramount. PARAMOUNT ACTED AS PLACEMENT AGENT FOR THE COMPANY'S PRIVATE EQUITY PLACEMENT CONDUCTED DURING JUNE THROUGH NOVEMBER OF 1996. SEVERAL EMPLOYEES OF THE COMPANY ARE OR PREVIOUSLY WERE AFFILIATED WITH PARAMOUNT. See "Certain Transactions." Harris Kanzer is the father of Steve H. Kanzer, C.P.A., ESQ., the Chairman of the Board of Directors and a stockholder of the Company. Marc Florin and Martin Kratchman are registered representatives of Paramount.

SHARES ELIGIBLE FOR FUTURE SALES

Upon completion of the Offering, the Company will have 17,298,909 shares of Common Stock outstanding or issuable upon the conversion of the Series A Preferred Stock and the exercise of all outstanding options and warrants as of January 2, 1997. Of these shares, the 12,101,409 shares registered in the Offering will be freely tradeable without restriction or further registration under the Securities Act, except that (i) any shares purchased by "affiliates" of the Company, as the term is defined under the Securities Act ("Affiliates"), may generally only be sold in compliance with the limitations of Rule 144 described below and (ii) such registered shares that are subject to certain lock-up provisions discussed below. In addition, the Company believes that there are no shares of Common Stock that are eligible for sale without restriction or further registration under the Securities Act, subject to certain requirements. See "Risk Factors--Potential Adverse Effect of Shares Eligible For Future Sales."

SALES OF RESTRICTED SHARES

The Company believes that 4,512,000 outstanding shares of Common Stock are "restricted securities" and under certain circumstances may, in the future, be sold in compliance with Rule 144. Assuming the availability of Rule 144, the Company believes that 1,132,500 "restricted" shares of Common Stock are currently eligible for sale and that an additional 3,379,500 "restricted" shares of Common Stock will be eligible for sale in 1998 and 1999, in each case so long as there is adequate current public information with respect to the Company as contemplated by Rule 144, as well as, certain volume limitations and manner of sale requirements imposed by Rule 144.

In general, under Rule 144, subject to the satisfaction of certain other conditions, a person, including an affiliate of the Company, who beneficially owned restricted shares of Common Stock for at least two years is entitled to sell, within any three-month period, a number of shares that does not exceed the greater of one percent of the total number of outstanding shares of the same class, or if the Common Stock is quoted on the Nasdaq Small-Cap Market or a national securities

61

exchange, the average weekly trading volume during the four calendar weeks immediately preceding the sale. A person who presently is not and who has not been an affiliate of the Company for at least three months immediately preceding the sale and who has beneficially owned the shares of Common Stock for at least three years is entitled to sell such shares under Rule 144(K) without regard to the volume limitations described above. THE COMMISSION HAS RECENTLY ADOPTED REVISIONS TO RULE 144 AND RULE 144(K), THE EFFECT OF WHICH WILL BE TO SHORTEN THE HOLDING PERIOD UNDER RULE 144 FROM TWO YEARS TO ONE YEAR AND TO SHORTEN THE HOLDING PERIOD UNDER RULE 144(K) FROM THREE YEARS TO TWO YEARS.

Prior to the Offering, there has been no public market for the Common Stock and no predictions can be made of the effect, if any, that the sale or availability for sale of "RESTRICTED" SHARES OR locked-up shares will have on the market price of the Common Stock. Nevertheless, sales of substantial amounts of such shares in the public market, or the perception that such sales could occur, could adversely affect the market price of the Common Stock and could impair the Company's future ability to raise capital through an offering of its equity securities.

For a description of the Company's outstanding warrants and options, See "Description of Securities--Stock Options" and "--Placement Agent Warrants."

PLAN OF DISTRIBUTION

The Selling Securityholders may, but are not required to, sell, directly or through brokers, the shares of Common Stock in negotiated transactions or in one or more transactions in the market at the price prevailing at the time of sale. (Certain of the Common Stock is subject to a lock-up agreement. See "Description of Securities--Lock-Up Agreements".) In connection with such sales, the Selling Securityholders and any participating broker may be deemed to be "underwriters" of the shares of Common Stock within the meaning of the Securities Act, although the offering of these securities will not be underwritten by a broker-dealer firm. Sales in the market may be made to broker-dealers making a market in the Common Stock or other broker-dealers, and such broker-dealer, upon their resale of such securities, may be deemed to be "Selling Securityholders" in this offering. The Company will not receive any of the proceeds from the sale of the Common Stock by the Selling Securityholders. Pursuant to the terms under which the Common Stock, the Series A Preferred Stock and Placement Agent Warrants were issued and sold, the Company has agreed to indemnify the Selling Securityholders against such liabilities they may incur as a result of any untrue statement of a material fact in the Registration Statement of which this Prospectus forms a part, or any omission herein or therein to state a material fact necessary in order to make the statements made, in the light of the circumstances under which they were made, not misleading. Such indemnification includes liabilities that the Selling Securityholders may incur under the Securities Act.

The Company will bear all costs and expenses of the registration under the Securities Act and certain state securities laws of the Common Stock and any discounts or commissions payable with respect to sales of such securities.

From time to time, this Prospectus will be supplemented and amended as required by the Securities Act. During any time when a supplement or amendment is so required, after notice from the Company, the Selling Securityholders are required to cease sales until the Prospectus has been supplemented or amended.

The Selling Securityholders have advised the Company that they may sell, directly or through brokers, all or a portion of the securities offered hereby in negotiated transactions or in one or more transactions in the market at the price prevailing at the time of sale. In connection with such sales, the Selling Securityholders and any participating broker may be deemed to be "underwriters" of the Common Stock within the meaning of the Securities Act of 1933. It is anticipated that usual and customary brokerage fees will be paid by the Selling Securityholders in all open market transactions. The Company will pay all other expenses of this Offering. The Company will advise the Selling Securityholders that no NASD member participating in the offering of the shares of Common Stock being offered hereby by the Selling Securityholders may receive compensation in excess of 8% of the proceeds of the sale of such shares. In addition, the terms and arrangements of any underwritten offering must be filed with the NASD for its review pursuant to Section 2710 of the NASD's Corporate Financing Rules.

The Company will inform the Selling Securityholders that the anti-manipulation provisions of Regulation M under the Securities Exchange Act of 1934 may apply to the sales of their shares offered hereby. The Company will advise the Selling Securityholders of the requirement for delivery of this Prospectus in connection with any sale of the Common Stock offered hereby.

Certain Selling Securityholders may from time to time purchase shares of Common Stock in the open market. These Selling Securityholders have been notified that they should not commence any distribution of Common Stock unless they have terminated their purchasing and bidding for Common Stock in the open market as provided in applicable securities regulations, including, without limitation, Regulation M.

DISCOVERY LABORATORIES, INC.
(a development stage company)

NOTES TO FINANCIAL STATEMENTS

(NOTE A) - The Company and Basis of Presentation:

Discovery Laboratories, Inc. (the "Company") was incorporated in Delaware on May 18, 1993 as MicroBio, Inc. The Company is a development stage company formed to license and develop pharmaceutical products to treat a variety of human diseases. The consolidated financial statements include the accounts of the Company and its 75% owned subsidiary Acute Therapeutics, Inc. (see Note G). Intercompany balances and transactions have been eliminated.

In November 1996 the Company completed a private placement of its securities and received aggregate net proceeds of approximately $19,000,000 (see Note F).

(NOTE B) - Summary of Significant Accounting Policies:

[1] Cash and cash equivalents:

The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents.

[2] Computer equipment:

Computer equipment is recorded at cost. Depreciation is computed using the straight-line method over the useful lives of the assets (five years).

[3] License fees:

License fees are capitalized and are being amortized on a straight-line basis over their respective terms of 15 to 17 years.

[4] Research and development:

Research and development costs are charged to operations as incurred.

[5] Use of estimates:

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

NOTES TO FINANCIAL STATEMENTS

(NOTE B) - Summary of Significant Accounting Policies: (continued)

[6] Stock-based compensation:

During 1996, the Company adopted Statement of Financial Accounting Standards, No. 123, "Accounting for Stock-Based Compensation" ("SFAS No. 123"). The provisions of SFAS No. 123 allow companies to either expense the estimated fair value of stock options or to continue to follow the intrinsic value method set forth in APB Opinion 25, "Accounting for Stock Issued to Employees" ("APB 25") but disclose the pro forma effects on net income (loss) had the fair value of the options been expensed. The Company has elected to continue to apply APB 25 in accounting for its stock option incentive plans. See Note H to the financial statements for further information.

[7] Net loss per share:

Net loss per share is computed based on the weighted average number of common shares outstanding for the periods. Common stock equivalents are antidilutive and therefore excluded from the calculation.

(NOTE C) - Employment Agreements:

An employment agreement with the Company's president provides for an annual salary of $175,000 through April 1999. Employment agreements with two executive officers provide for aggregate annual salaries of $295,000 through December 1999, subject to certain increases.

(NOTE D) - Income Taxes:

At December 31, 1996, the Company has available for federal income tax purposes net operating loss carryforwards of approximately $350,000 expiring through 2011, that may be used to offset future taxable income.

The principal difference between the deficit accumulated during the development stage for financial reporting purposes and the net operating loss carryforward for tax purposes is primarily due to the write-off of the acquired research and development supplies and to certain general and administrative costs which are not currently deductible for tax purposes. The Company has provided a valuation reserve against the full amount of the deferred tax asset arising from net operating loss benefit of approximately $130,000, the research and

NOTES TO FINANCIAL STATEMENTS

(NOTE D) - Income Taxes: (continued)

development write-off of approximately $850,000 and general and administrative costs of approximately $250,000 since the likelihood of realization cannot be determined. The valuation reserve increased by approximately $1,223,000 and $7,000 for the years ended December 31, 1996 and December 31, 1995, respectively. Pursuant to Section 382 of the Internal Revenue Code, the utilization of this carryforward may be limited due to ownership changes which have occurred or may occur.

(NOTE E) - License Agreements:

[1] The Company entered into a license agreement with the Charlotte-Mecklenburg Hospital Authority for the use of the active compound in SuperVent, a therapy which the Company is clinically testing. The Company paid a license issue fee of $86,400 and has agreed to pay royalties on future sales and to pay future patent- related costs. The license expires upon expiration of the underlying patents.

[2] The Company entered into a license agreement with the Wisconsin Alumni Research Foundation ("WARF") for the use of the patented compound ST-630 in the treatment of post-menopausal osteoporosis. The Company paid WARF an option fee of $25,000 in June 1996 and a license issue fee of $400,000 in October 1996 and is obligated to make future milestone payments aggregating $3,095,000 and pay royalties on future sales.

(NOTE G) - Investment in Acute Therapeutics, Inc.:

[1] Formation of Acute Therapeutics, Inc.:

On October 28, 1996, the Company invested $7.5 million in a newly formed subsidiary, Acute Therapeutics, Inc. ("ATI"), in exchange for 600,000 shares of Series A convertible preferred stock of ATI, representing 75% of the outstanding voting securities of ATI following such transaction.

Concurrently with the Company's investment in ATI, Johnson & Johnson, Inc. ("J & J"), J & J's wholly-owned subsidiary, Ortho Pharmaceuticals, Inc., and ATI entered into an agreement (the "J & J License Agreement") granting an exclusive license of KL4-Surfactant technology to ATI in exchange for certain license fees ($200,000 of which was paid in November 1996), milestone payments aggregating $2,750,000, royalties and 40,000 shares of ATI common stock. J & J contributed its KL4-Surfactant raw material inventory and manufacturing equipment to ATI in exchange for 2,200 shares of nonvoting Series B preferred stock of ATI having a $2.2 million liquidation preference and a $100 per share cumulative dividend. The inventory and equipment were valued at $2,200,000 (the value of the preferred shares issued to J & J) and were charged to expense as their intended use is for research and development activities. The Scripps Research Institute received 40,000 shares of common stock of ATI in exchange for its consent to the J & J License Agreement.

The founders of ATI purchased an aggregate of 120,000 shares of ATI common stock for $.01 per share and were granted options to purchase an aggregate of 44,800 shares of common stock of ATI at an exercise price of $.01 per share vesting after a five-year term, subject to acceleration and 40,000 shares of common stock of ATI at an exercise price of $.32 per share vesting in April 1997.

ATI also entered into various two-year consulting agreements providing for aggregate annual fees of $300,000 plus royalties on net commercial sales of licensed products sold by ATI or its sublicensees and an 18-month consulting agreement providing for monthly fees of $7,500.

ATI leases its office and laboratory space pursuant to an operating lease requiring aggregate annual payments of approximately $67,000 through November 2001.

[3] ATI stock option plan:

ATI adopted the 1996 Stock Option/Stock Issuance Plan (the "ATI Plan") consisting of a Discretionary Option Grant program for employees and an Automatic Option Grant Program under which option grants will automatically be made at periodic intervals to eligible nonemployee directors to purchase shares of common stock, in either case at an exercise price equal to at least 85% of the fair market value of the common stock on the grant date. Under the Discretionary Option Grant program, options will be granted to employees either as incentive stock options or nonstatutory options and will vest over a specified period of time (generally three to five years) as determined by the ATI Board of Directors. ATI has reserved 234,800 shares of common stock for issuance under these plans. Options for 173,800 shares of common stock have been granted through January 1997.

(NOTE H) - Stock Options:

In November 1996, the Company adopted its 1996 Stock Option/Stock Issuance Plan which includes three equity programs (the "Discovery Plan"). Under the Discretionary Option Grant Program, options to acquire shares of the Company's common stock may be granted to eligible persons who are employees, nonemployee directors, consultants and other independent advisors. Pursuant to the Stock Issuance Program, such eligible persons may be issued shares of the Company's common stock directly and under the Automatic Option Grant Program, eligible directors will automatically receive option grants at periodic intervals. The maximum number of shares of common stock which maybe issued over the term of plan shall not exceed 1,250,000.

NOTES TO FINANCIAL STATEMENTS

(NOTE H) - Stock Options: (continued)

In July and August, 1996, options to purchase 100,000 shares of the Company's common stock were granted (all of which were immediately exercisable), with a weighted average exercise price of $.125 per share. Options to purchase 25,000 shares at $.10 per share were exercised in July 1996 and options to purchase 25,000 shares at $.20 per share were exercised in November 1996.

The Company applies APB 25 in accounting for the Discovery Plan and the ATI Plan and, accordingly, recognizes compensation expense for the difference between the fair value of the underlying common stock and the exercise price of the option at the date of grant. The effect of applying SFAS No. 123 on pro forma net loss is not necessarily representative of the effects on reported net income or loss for future years due to, among other things, (1) the vesting period of the stock options and the (2) fair value of additional stock options in future years. Had compensation cost for the Company's stock option plans been determined based upon the fair value of the options at the grant date of awards under the plans consistent with the methodology prescribed under SFAS No. 123, the Company's net loss in 1996 would have been approximately $3,248,000 or $.77 per share. The fair value of the options granted are estimated as $.06 and $7 per share for the Discovery Plan and the ATI Plan, respectively, on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: dividend yield 0%, volatility of 0%, risk-free interest rate of 6.7% for 1996, and expected life of ten years.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law ("Section 145") authorizes a court to award or a corporation's Board of Directors to grant indemnification to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended (the "Securities Act"). Article Tenth of Discovery's Certificate of Incorporation provides that the Corporation shall indemnify and advance expenses to its directors ands officers to the fullest extent permitted by Section 145 of the Delaware General Corporation Law. Article Ninth of Discovery's Certificate of Incorporation provides that the liability of its directors is eliminated to the fullest extent permitted by Section 102(b)(7) of the Delaware General Corporation Law. These provisions in the Certificate of Incorporation do not eliminate the directors' fiduciary duty, and in appropriate circumstances equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to the Company for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for actions leading to improper personal benefit to the director, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provisions also do not affect a director's responsibilities under any other law, such as the federal securities laws or state or federal environmental laws. Reference is made to Section 5.6 of the Subscription Agreements relating to the Unit Offering (Exhibit 4.3), Section of the Common Placement Warrant (Exhibit 4.7) and Section of the Preferred Placement Warrant (Exhibit 4.8) indemnifying against certain liabilities certain of the Company's stockholders or Paramount Capital, Inc., a company wholly owned by Lindsay A. Rosenwald, M.D., who also is the Chief Executive Officer of and a shareholder in RAQ, LLC, a substantial shareholder of the Company.


ITEM 25. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

The following table sets forth the costs and expenses, other than underwriting discounts and commissions, payable by the Company in connection with the sale of securities being registered. The following table includes costs and expenses relating to securities being registered for resale by certain securityholders, all of which will be paid by the Company. All amounts are estimates except the SEC registration fee and the Nasdaq filing fees.

ITEM 28. UNDERTAKINGS

The Company hereby undertakes that it will:

(1)          File, during any period in which it offers or sells
             securities, a post-effective amendment to this registration
             statement to:

    (i)      Include any prospectus required by section 10(a)(3) of the
             Securities Act;

    (ii)     Reflect in the prospectus any facts or events which,
             individually or together, represent a fundamental change in
             the information in the registration statement; and
             notwithstanding the foregoing, any increase or decrease in
             volume of securities offered (if the total dollar value of
             securities offered would not exceed that which was registered)
             and any deviation from the low or high end of the estimated
             maximum offering range may be reflected in the form of
             prospectus filed with the Commission pursuant to Rule 424(b)
             if, in the aggregate, the changes in the volume and price
             represent no more than a 20% change in the maximum aggregate
             offering price set forth in the "Calculation of Registration
             Fee" table in the effective registration statement;

    (iii)    Include any additional or changed material information on the
             plan of distribution.

(2) For determining liability under the Securities Act, treat each post-effective amendment as a new registration statement of the securities offered, and the offering of the securities at that time to be the initial BONA FIDE offering.

(3) File a post-effective amendment to remove from registration any of the securities that remain unsold at the end of the offering.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the Delaware General Corporation Law, the Certificate of Incorporation or the By-Laws of the Company, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer, or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The Company hereby undertakes that it will:

(1) For determining any liability under the Securities Act, treat the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Company pursuant to Rule 424(b)(1), or (4) or 497(h) under the Securities Act as part of this registration statement as of the time it was declared effective.

(2) For determining any liability under the Securities Act, treat each post-effective amendment that contains a form of prospectus as a new registration statement for the securities offered in the registration statement, and that offering of such securities at that time as the initial BONA FIDE offering of those securities.

              SIXTH: The corporation is to have perpetual existence.

-1-

SEVENTH: Whenever a compromise or arrangement is proposed between this corporation and its creditors or any class of them and/or between this corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of this corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for this corporation under the provisions of ss. 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for this corporation under the provisions of ss. 279 of Title 8 of the Delaware Code order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of this corporation as consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of this corporation, as the case may be, and also on this corporation.

EIGHTH: For the management of the business and for the conduct of the affairs of the corporation, and in further definition, limitation, and regulation of the powers of the corporation and of its directors and of its stockholders or any class thereof, as the case may be, it is further provided:

1. The management of the business and the conduct of the affairs of the corporation shall be vested in its Board of Directors. The number of directors which shall constitute the whole Board of Directors shall be fixed by, or in the manner provided in, the Bylaws. The phrase "whole Board" and the phrase "total number of directors" shall be deemed to have the same meaning, to wit, the total number of directors which the corporation would have if there were no vacancies. No election of directors need be by written ballot.

2. After the original or other Bylaws of the corporation have been adopted, amended, or repealed, as the case may be, in accordance with the provisions of ss. 109 of the General Corporation Law of the State of Delaware, and, after the corporation has received any payment for any of its Stock, the power to adopt, amend, or repeal the Bylaws of the corporation may be exercised by the Board of Directors of the corporation; provided, however, that any provision for the classification of directors of the corporation for staggered terms pursuant to the provisions of subsection (d) of ss. 141 of the General Corporation Law of the State of Delaware shall be set forth in an initial Bylaw or in a Bylaw adopted by the stockholders entitled to vote of the

-2-

corporation unless provisions for such classification shall be set forth in this certificate of incorporation.

3. Whenever the corporation shall be authorized to issue only one class of stock, each outstanding share shall entitle the holder thereof to notice of, and the right to vote at, any meeting of stockholders. Whenever the incorporation shall be authorized to issue more than one class of stock, no outstanding share of any class of stock which is denied voting power under the provisions of the certificate of incorporation shall entitle the holder thereof to the right to vote at any meeting of stockholders except as the provisions of paragraph (2) of subsection (b) of ss. 242 of the General Corporation Law of the State of Delaware shall otherwise require; provided, that no share of any such class which is otherwise denied voting power shall entitle the holder thereof to vote upon the increase or decrease in the number of authorized shares of said class.

NINTH: The personal liability of the directors of the corporation is hereby eliminated to the fullest extent permitted by the provisions of paragraph (7) of subsection (b) of ss. 102 of the General Corporation Law of the State of Delaware, as the same may be amended and supplemented.

TENTH: The corporation shall, to the fullest extent permitted by the provisions of ss. 145 of the General Corporation Law of the State of Delaware, as the same may be amended and supplemented, indemnify any and all persons whom it shall have power to indemnify under said section from and against any and all of the expenses, liabilities, or other matters referred to in or covered by said section, and the indemnification provided for herein shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any Bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee, or agent and shall inure to the benefit of the heirs, executors, and administrators of such a person.

ELEVENTH: From time to time any of the provisions of this certificate of incorporation may be amended, altered, or repealed, and other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted in the manner and at the time prescribed by said laws, and all rights at any time conferred upon the stockholders of the corporation by this certificate of incorporation are granted subject to the provisions of this Article ELEVENTH.

[FORM OF]

CERTIFICATE OF DESIGNATIONS

of

SERIES A CONVERTIBLE PREFERRED STOCK

of

DISCOVERY LABORATORIES, INC.

Pursuant to Section 151 of the

General Corporation Law of the State of Delaware

DISCOVERY LABORATORIES, INC., a corporation organized and existing under the laws of the State of Delaware (the "Corporation"), does hereby certify that, pursuant to the authority conferred on the Board of Directors of the Corporation by the Certificate of Incorporation, as amended, of the Corporation and in accordance with Section 151 of the General Corporation Law of the State of Delaware, the Board of Directors of the Corporation adopted the following resolution establishing a series of 3,000,000 shares of Preferred Stock of the Corporation designated as "Series A Convertible Preferred Stock":

RESOLVED, that pursuant to the authority conferred on the Board of Directors of this Corporation by the Certificate of Incorporation, as amended, a series of Preferred Stock, par value $.001 per share, of the Corporation is hereby established and created, and that the designation and number of shares thereof and the voting and other powers, preferences and relative, participating, optional or other rights of the shares of such series and the qualifications, limitations and restrictions thereof are as follows:

Series A Convertible Preferred Stock

1. Designation and Amount. There shall be a series of Preferred Stock designated as "Series A Convertible Preferred Stock" and the number of shares constituting such series shall be 3,000,000. Such series is referred to herein as the "Series A Convertible Preferred Stock". Such number of shares may be increased or decreased by resolution of the Board of Directors of the Corporation; provided, however, that no decrease shall reduce the number of shares of Series A Convertible Preferred Stock to less than the number of shares then issued and outstanding.

2. Dividends. Subject to the prior and superior rights of the holders of any shares of any series or class of capital stock ranking prior and superior to the shares of Series A Convertible Preferred Stock with respect to dividends and distributions, the holders of shares of Series A Convertible Preferred Stock, shall

-1-

be entitled to receive dividends and distributions, when, as and if declared by the Board of Directors out of funds legally available for such purpose. If the Corporation declares a dividend or distribution on the common stock, par value $.001 per share (the "Common Stock"), of the Corporation, the holders of shares of Series A Convertible Preferred Stock shall be entitled to receive for each share of Series A Convertible Preferred Stock a dividend or distribution in the amount of the dividend or distribution that would be received by a holder of the Common Stock into which such share of Series A Convertible Preferred Stock is convertible on the record date for such dividend or distribution. If the Corporation declares a dividend or distribution on any other class or series of preferred stock, the holders of shares of Series A Convertible Preferred Stock shall be entitled to receive a dividend or distribution in an amount per share in proportion to the dividend or distribution declared on a share of such other class or series based upon the liquidation preference of a share of the Series A Convertible Preferred Stock relative to that of a share of such other class or series, unless the holders of at least 66.67% of the outstanding shares of Series A Convertible Preferred Stock consent otherwise. In any such case, the Corporation shall declare a dividend or distribution on the Series A Convertible Preferred Stock at the same time that it declares a dividend or distribution on the Common Stock or such other class or series of preferred stock and shall establish the same record date for the dividend or distribution on the Series A Convertible Preferred Stock as is established for such dividend or distribution on the Common Stock or such other class or series of preferred stock. Each such dividend or distribution will be payable to holders of record of the Series A Convertible Preferred Stock as they appeared on the records of the Corporation at the close of business on the record date declared for such dividend or distribution, as shall be fixed by the Board of Directors. Any dividend or distribution payable to the holders of the Series A Preferred Stock pursuant to this Section 2 shall be paid to such holders at the same time as the dividend or distribution on the Common Stock by which it is measured or paid. If the corporation declares or pays a dividend or distribution on the Series A Convertible Preferred Stock as a result of the declaration or payment of a dividend or distribution on the Common Stock or any other class or series of preferred stock as described above, the holders of the Series A Convertible Preferred Stock shall not be entitled to any additional dividend or distribution solely because such first dividend or distribution also required the declaration or payment of a dividend or distribution on any other class or series of preferred stock. Any reference to "dividend" or "distribution" contained in this
Section 2 shall not be deemed to include any dividend or distribution made in connection with or in lieu of any Liquidation Event (as defined below).

3. Liquidation Preference. In the event of a (i) liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary,
(ii) a sale or other disposition of all or substantially all of the assets of the Corporation or (iii) any consolidation, merger, combination, reorganization or other transaction in which the Corporation is not the surviving entity or the shares of Common Stock constituting in excess of 50% of the voting power of the Corporation are exchanged for or changed into other stock or securities, cash and/or any other property (a "Merger Transaction") (subparagraphs (i), (ii) and
(iii) being collectively referred to as a "Liquidation Event"), after payment or provision for payment of debts and other liabilities of the Corporation, the holders of the Series A Convertible Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its shareholders, whether such assets are capital, surplus, or earnings, before any payment or declaration and setting apart for payment of any amount shall be made in respect of the stock junior to the Series A Convertible Preferred Stock, an amount equal to $13.50 per share plus an amount equal to all declared and unpaid dividends thereon; provided, however, in the case of Section 3(iii) above, such $13.50 per share may be paid in cash and/or securities (valued at the closing price (as defined in Section 5) of such security) of the entity surviving such Merger Transaction. If upon any Liquidation Event, whether voluntary or involuntary, the assets to be distributed to the holders of the Series A Convertible Preferred Stock shall be insufficient to permit the payment to such shareholders of the full preferential amounts aforesaid, then all of the assets of the Corporation to be distributed shall be so distributed ratably to the holders of the Series A Convertible Preferred Stock on the basis of the number of shares of Series A Convertible Preferred Stock held. A consolidation or merger of the Corporation with or into another corporation, other than in a transaction described in Section 3(iii) above, shall not be considered a liquidation, dissolution or winding up of the

-2-

Corporation or a sale or other disposition of all or substantially all of the assets of the Corporation and accordingly the Corporation shall make appropriate provision to ensure that the terms of this Certificate of Designations survive any such transaction. All shares of Series A Convertible Preferred Stock shall rank as to payment upon the occurrence of any Liquidation Event senior to the Common Stock as provided herein and, unless the terms of such series shall provide otherwise, senior to all other series of the Corporation's preferred stock.

4. Conversion.

(a) Right of Conversion. The shares of Series A Convertible Preferred Stock shall be convertible, in whole or in part, at the option of the holder thereof and upon notice to the Corporation as set forth in paragraph (b) below, into fully paid and nonassessable shares of Common Stock and such other securities and property as hereinafter provided. The shares of Series A Convertible Preferred Stock shall be convertible initially at the rate of 4.0 shares of Common Stock for each full share of Series A Convertible Preferred Stock and shall be subject to adjustment as provided herein. The initial conversion price per share of Common Stock is $2.50 and shall be subject to adjustment as provided herein. For purposes of this resolution, the "conversion rate" applicable to a share of Series A Convertible Preferred Stock shall be the number of shares of Common Stock and number or amount of any other securities and property as hereinafter provided into which a share of Series A Convertible Preferred Stock is then convertible and shall be determined by dividing the then existing conversion price into $10.00.

The conversion price (subject to adjustments pursuant to the provisions of paragraph (c) below) in effect immediately prior to the date (the "Reset Date") that is 12 months after the effective date of the shelf registration statement covering the shares of Common Stock issuable upon conversion of the Series A Convertible Preferred Stock shall be adjusted and reset effective as of the Reset Date if the average closing bid price of the Common Stock for the 30 consecutive trading days immediately preceding the Reset Date (the "12-Month Trading Price") is less than 135% of the then applicable conversion price (a "Reset Event"). Upon the occurrence of a Reset Event, the conversion price shall be reduced to be equal to the greater of (A) the 12-Month Trading Price divided by 1.35 and (B) 50% of the then applicable conversion price. If there is any change in the conversion price as a result of the preceding sentence, then the conversion rate shall be changed accordingly, and shall be determined by dividing the new conversion price into $10.00. The Corporation shall prepare a certificate signed by the principal financial officer of the Corporation setting forth the conversion rate as of the Reset Date, showing in reasonable detail the facts upon which such conversion rate is based, and such certificate shall be forthwith filed with the transfer agent of the Series A Convertible Preferred Stock. Notwithstanding the provisions of subparagraph (vi) of paragraph (c) below, a notice stating that the conversion rate has been adjusted pursuant to this paragraph, or that no adjustment is necessary, and setting forth the conversion rate in effect as of the Reset Date shall be mailed as promptly as practicable after the Reset Date by the Corporation to all record holders of the Series A Convertible Preferred Stock at their last addresses as they shall appear in the stock transfer books of the Corporation.

The "closing bid price" for each trading day shall be the reported closing bid price on the NASDAQ Small-Cap Market or the NASDAQ National Market System (collectively referred to as, "NASDAQ") or, if the Common Stock is not quoted on NASDAQ, on the principal national securities exchange on which the Common Stock is listed or admitted to trading (based on the aggregate dollar value of all securities listed or admitted to trading) or, if not listed or admitted to trading on any national securities exchange or quoted on NASDAQ, the closing bid price in the over-the-counter market as furnished by any NASD member firm selected from time to time by the Corporation for that purpose, or, if such prices are not available, the fair market value set by, or in a manner established by, the Board of Directors of the Corporation in good faith. "Trading day" shall mean a day on which the national securities exchange or NASDAQ used to determine the closing bid price is open

-4-

for the transaction of business or the reporting of trades or, if the closing bid price is not so determined, a day on which NASDAQ is open for the transaction of business.

(b) Conversion Procedures. Any holder of shares of Series A Convertible Preferred Stock desiring to convert such shares into Common Stock shall surrender the certificate or certificates evidencing such shares of Series A Convertible Preferred Stock at the office of the transfer agent for the Series A Convertible Preferred Stock, which certificate or certificates, if the Corporation shall so require, shall be duly endorsed to the Corporation or in blank, or accompanied by proper instruments of transfer to the Corporation or in blank, accompanied by irrevocable written notice to the Corporation that the holder elects so to convert such shares of Series A Convertible Preferred Stock and specifying the name or names (with address) in which a certificate or certificates evidencing shares of Common Stock are to be issued. The Corporation need not deem a notice of conversion to be received unless the holder complies with all the provisions hereof. The Corporation will instruct the transfer agent (which may be the Corporation) to make a notation of the date that a notice of conversion is received, which date shall be deemed to be the date of receipt for purposes hereof.

The Corporation shall, as soon as practicable after such deposit of certificates evidencing shares of Series A Convertible Preferred Stock accompanied by the written notice and compliance with any other conditions herein contained, deliver at such office of such transfer agent to the person for whose account such shares of Series A Convertible Preferred Stock were so surrendered, or to the nominee or nominees of such person, certificates evidencing the number of full shares of Common Stock to which such person shall be entitled as aforesaid, together with a cash adjustment of any fraction of a share as hereinafter provided. Subject to the following provisions of this paragraph, such conversion shall be deemed to have been made as of the date of such surrender of the shares of Series A Convertible Preferred Stock to be converted, and the person or persons entitled to receive the Common Stock deliverable upon conversion of such Series A Convertible Preferred Stock shall be treated for all purposes as the record holder or holders of such Common Stock on such date; provided, however, that the Corporation shall not be required to convert any shares of Series A Convertible Preferred Stock while the stock transfer books of the Corporation are closed for any purpose, but the surrender of Series A Convertible Preferred Stock for conversion during any period while such books are so closed shall become effective for conversion immediately upon the reopening of such books as if the surrender had been made on the date of such reopening, and the conversion shall be at the conversion rate in effect on such date. No adjustments in respect of any dividends on shares surrendered for conversion or any dividend on the Common Stock issued upon conversion shall be made upon the conversion of any shares of Series A Convertible Preferred Stock.

All notices of conversion shall be irrevocable; provided, however, that if the Corporation has sent notice of an event pursuant to Sections 4(f) and (g) hereof, a holder of Series A Convertible Preferred Stock may, at its election, provide in its notice of conversion that the conversion of its shares of Series A Convertible Preferred Stock shall be contingent upon the occurrence of the record date or effectiveness of such event (as specified by such holder), provided that such notice of conversion is received by the Corporation prior to such record date or effective date, as the case may be.

(c) Certain Adjustments of Conversion Rate. In addition to adjustment pursuant to paragraph (a) above, the conversion rate (and the corresponding conversion price) shall be subject to adjustment from time to time as follows:

(i) In case the Corporation shall (A) pay a dividend in Common Stock or make a distribution in Common Stock, (B) subdivide its outstanding Common Stock, (C) combine its outstanding Common Stock into a smaller number of shares of Common Stock or (D) issue by reclassification of its Common Stock other securities of the Corporation, then in each such case the conversion rate in effect immediately prior thereto shall be adjusted so that the holder of any shares of

-4-

Series A Convertible Preferred Stock thereafter surrendered for conversion shall be entitled to receive the kind and number of shares of Common Stock or other securities of the Corporation which such holder would have owned or would have been entitled to receive immediately after the happening of any of the events described above had such shares of Series A Convertible Preferred Stock been converted immediately prior to the happening of such event or any record date with respect thereto. Any adjustment made pursuant to this subparagraph
(i) shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.

(ii) In case the Corporation shall issue rights, options, warrants or convertible securities to all or substantially all holders of its Common Stock, without any charge to such holders, entitling them to subscribe for or purchase Common Stock at a price per share which is lower at the record date mentioned below than both (A) the then effective conversion price and (B) the closing bid price (as defined in
Section 4) for the trading day immediately prior to such record date (the "Current Market Price"), then the conversion rate shall be determined by multiplying the conversion rate theretofore in effect by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding immediately prior to the issuance of such rights, options, warrants or convertible securities plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the denominator shall be the number of shares of Common Stock outstanding immediately prior to the issuance of such rights, options, warrants or convertible securities plus the number of shares which the aggregate offering price of the total number of shares offered would purchase at such Current Market Price. Such adjustment shall be made whenever such rights, options, warrants or convertible securities are issued, and shall become effective immediately and retroactive to the record date for the determination of stockholders entitled to receive such rights, options, warrants or convertible securities. Notwithstanding any of the foregoing, no adjustment shall be made pursuant to the provisions of this subsection (ii), if such adjustment would result in a decrease of the conversion rate.

(iii) In case the Corporation shall distribute to all or substantially all holders of its Common Stock evidences of its indebtedness or assets (excluding cash dividends or distributions out of earnings) or rights, options, warrants or convertible securities containing the right to subscribe for or purchase Common Stock (excluding those referred to in subparagraph (ii) above), then in each case the conversion rate shall be determined by multiplying the conversion rate theretofore in effect by a fraction, of which the numerator shall be the then fair value as determined in good faith by the Corporation's Board of Directors on the date of such distribution, and of which the denominator shall be such fair value on such date minus the then fair value (as so determined) of the portion of the assets or evidences of indebtedness so distributed or of such subscription rights, options, warrants or convertible securities applicable to one share. Such adjustment shall be made whenever any such distribution is made and shall become effective on the date of distribution retroactive to the record date for the determination of stockholders entitled to receive such distribution.

(iv) Upon the expiration of any rights, options, warrants or conversion privileges, if such shall not have been exercised, the conversion rate shall, upon such expiration, be readjusted and shall thereafter be such as it would have been had it been originally adjusted (or had the original adjustment not been required, as the case may be) on the basis of (A) the fact that Common Stock, if any, actually issued or sold upon the exercise of such rights, options, warrants or conversion privileges, and (B) the fact that such shares of Common Stock, if any, were issued or sold for the consideration actually received by the Corporation upon such exercise plus the consideration, if any, actually received by the Corporation for the issuance, sale or grant of all such rights, options, warrants or conversion privileges whether or not exercised.

-5-

(v) No adjustment in the conversion rate shall be required unless such adjustment would require an increase or decrease of at least 1% in such rate; provided, however, that the Corporation may make any such adjustment at its election; and provided, further, that any adjustments which by reason of this subparagraph (v) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 4 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be.

(vi) Whenever the conversion rate is adjusted as provided in any provision of this Section 4:

(A) the Corporation shall compute (or may retain a firm of independent public accountants of recognized national standing (which may be any such firm regularly employed by the Corporation) to compute) the adjusted conversion rate in accordance with this Section 4 and shall prepare a certificate signed by the principal financial officer of the Corporation (or cause any such independent public accountants to execute a certificate) setting forth the adjusted conversion rate and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed with the transfer agent of the Series A Convertible Preferred Stock; and

(B) a notice stating that the conversion rate has been adjusted and setting forth the adjusted conversion rate shall forthwith be required, and as soon as practicable after it is required, such notice shall be mailed by the Corporation to all record holders of Series A Convertible Preferred Stock at their last addresses as they shall appear in the stock transfer books of the Corporation.

(vii) In the event that at any time, as a result of any adjustment made pursuant to this Section 4, the holder of any shares of Series A Convertible Preferred Stock thereafter surrendered for conversion shall become entitled to receive any shares of the Corporation other than shares of Common Stock or to receive any other securities, the number of such other shares or securities so receivable upon conversion of any share of Series A Convertible Preferred Stock shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions contained in this Section 4 with respect to the Common Stock.

(d) No Fractional Shares. No fractional shares or scrip representing fractional shares of Common Stock shall be issued upon conversion of Series A Convertible Preferred Stock. If more than one certificate evidencing shares of Series A Convertible Preferred Stock shall be surrendered for conversion at one time by the same holder, the number of full shares issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series A Convertible Preferred Stock so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any shares of Series A Convertible Preferred Stock, the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount equal to the same fraction of the market price per share of Common Stock (which shall be the closing price as defined in Section 5) at the close of business on the day of conversion.

(e) Reservation of Shares; Transfer Taxes; Etc. The Corporation shall at all times reserve and keep available, out of its authorized and unissued stock, solely for the purpose of effecting the conversion of the Series A Convertible Preferred Stock, such number of shares of its Common Stock free of preemptive rights as shall from time to time be sufficient to effect the conversion of all shares of Series A Convertible Preferred Stock from time to time outstanding. The Corporation shall use its best efforts from time to time, in accordance with the laws of the State of Delaware, to increase the authorized number of shares of Common Stock if at any time the number of shares of Common Stock not outstanding shall not be sufficient to permit the

-6-

conversion of all the then-outstanding shares of Series A Convertible Preferred Stock.

The Corporation shall pay any and all issue or other taxes that may be payable in respect of any issue or delivery of shares of Common Stock on conversion of the Series A Convertible Preferred Stock. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of Common Stock (or other securities or assets) in a name other than that in which the shares of Series A Convertible Preferred Stock so converted were registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Corporation the amount of such tax or has established, to the satisfaction of the Corporation, that such tax has been paid.

Notwithstanding anything to the contrary herein, before taking any action that would cause an adjustment reducing the conversion rate or before any such adjustment is made as a result of a Reset Event, in either event, such that the effective conversion price (for all purposes an amount equal to $10.00 divided by the conversion rate as in effect at such time) would be below the then par value of the Common Stock, the Corporation shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and nonassessable shares of Common Stock at the conversion rate as so adjusted.

(f) Prior Notice of Certain Events. In case:

(i) the Corporation shall declare any dividend (or any other distribution) on its Common Stock; or

(ii) the Corporation shall authorize the granting to the holders of Common Stock of rights or warrants to subscribe for or purchase any shares of stock of any class or of any other rights or warrants; or

(iii) of any reclassification of Common Stock (other than a subdivision or combination of the outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Corporation is a party and for which approval of any stockholders of the Corporation shall be required, or of the sale or transfer of all or substantially all of the assets of the Corporation or of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or other property; or

(iv) of the voluntary or involuntary dissolution, liquidation or winding up of the Corporation or other Liquidation Event;

then the Corporation shall cause to be filed with the transfer agent for the Series A Convertible Preferred Stock, and shall cause to be mailed to the holders of record of the Series A Convertible Preferred Stock, at their last addresses as they shall appear upon the stock transfer books of the Corporation, at least 20 days prior to the applicable record date hereinafter specified, a notice stating (x) the date on which a record (if any) is to be taken for the purpose of such dividend, distribution or granting of rights or warrants or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined and a description of the cash, securities or other property to be received by such holders upon such dividend, distribution or granting of rights or warrants or (y) the date on which such reclassification, consolidation, merger, sale, transfer, share exchange, dissolution, liquidation or winding up is expected to become effective, the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such exchange, dissolution, liquidation, winding up or other Liquidation Event and the consideration, including

-7-

securities or other property, to be received by such holders upon such exchange; provided, however, that no failure to mail such notice or any defect therein or in the mailing thereof shall affect the validity of the corporate action required to be specified in such notice.

(g) Other Changes in Conversion Rate. The Corporation from time to time may increase the conversion rate by any amount for any period of time if the period is at least 20 days and if the increase is irrevocable during the period. Whenever the conversion rate is so increased, the Corporation shall mail to holders of record of the Series A Convertible Preferred Stock a notice of the increase at least 15 days before the date the increased conversion rate takes effect, and such notice shall state the increased conversion rate and the period it will be in effect.

The Corporation may make such increases in the conversion rate, in addition to those required or allowed by this Section 4, as shall be determined by it, as evidenced by a resolution of the Board of Directors, to be advisable in order to avoid or diminish any income tax to holders of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes.

(h) Ambiguities/Errors. The Board of Directors of the Corporation shall have the power to resolve any ambiguity or correct any error in the provisions relating to the convertibility of the Series A Convertible Preferred Stock, and its actions in so doing shall be final and conclusive.

5. Mandatory Conversion. At any time on or after the Reset Date, the Corporation, at its option, may cause the Series A Convertible Preferred Stock to be converted in whole, or in part, on a pro rata basis, into fully paid and nonassessable shares of Common Stock and such other securities and property as herein provided if the closing price of the Common Stock shall have exceeded 150% of the then applicable conversion price for at least 20 trading days in any 30 consecutive trading day period. Any shares of Series A Convertible Preferred Stock so converted shall be treated as having been surrendered by the holder thereof for conversion pursuant to Section 4 on the date of such mandatory conversion (unless previously converted at the option of the holder).

Not more than 60 nor less than 20 days prior to the date of any such mandatory conversion, notice by first class mail, postage prepaid, shall be given to the holders of record of the Series A Convertible Preferred Stock to be converted, addressed to such holders at their last addresses as shown on the stock transfer books of the Corporation. Each such notice shall specify the date fixed for conversion, the place or places for surrender of shares of Series A Convertible Preferred Stock, and the then effective conversion rate pursuant to Section 4.

The "closing price" for each trading day shall be the reported last sales price regular way or, in case no such reported sale takes place on such day, the average of the reported closing bid and asked prices regular way, in either case on the NASDAQ or, if the Common Stock is not quoted on NASDAQ, on the principal national securities exchange on which the Common Stock is listed or admitted to trading (based on the aggregate dollar value of all securities listed or admitted to trading) or, if not listed or admitted to trading on any national securities exchange or quoted on NASDAQ, the average of the closing bid and asked prices in the over-the-counter market as furnished by any NASD member firm selected from time to time by the Corporation for that purpose, or, if such prices are not available, the fair market value set by, or in a manner established by, the Board of Directors of the Corporation in good faith. "Trading day" shall have the meaning given in Section 4 hereof.

Any notice which is mailed as herein provided shall be conclusively presumed to have been duly given by the Corporation on the date deposited in the mail, whether or not the holder of the Series A Convertible

-8-

Preferred Stock receives such notice; and failure properly to give such notice by mail, or any defect in such notice, to the holders of the shares to be converted shall not affect the validity of the proceedings for the conversion of any other shares of Series A Convertible Preferred Stock. On or after the date fixed for conversion as stated in such notice, each holder of shares called to be converted shall surrender the certificate evidencing such shares to the Corporation at the place designated in such notice for conversion.
Notwithstanding that the certificates evidencing any shares properly called for conversion shall not have been surrendered, the shares shall no longer be deemed outstanding and all rights whatsoever with respect to the shares so called for conversion (except the right of the holders to convert such shares upon surrender of their certificates therefor) shall terminate.

6. Voting Rights.

(a) General. Except as otherwise provided herein, in the Certificate of Incorporation or the By-laws, the holders of shares of Series A Convertible Preferred Stock, the holders of shares of Common Stock and the holders of any other class or series of shares entitled to vote with the Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation. In any such vote, each share of Series A Convertible Preferred Stock shall entitle the holder thereof to cast the number of votes equal to the number of votes which could be cast in such vote by a holder of the Common Stock into which such share of Series A Convertible Preferred Stock is convertible on the record date for such vote, or if no record date has been established, on the date such vote is taken. Any shares of Series A Convertible Preferred Stock held by the Corporation or any entity controlled by the Corporation shall not have voting rights hereunder and shall not be counted in determining the presence of a quorum.

(b) Class Voting Rights. In addition to any vote specified in paragraph (a) of this Section 6, so long as 50% of the shares of Series A Convertible Preferred Stock (including those shares of Series A Convertible Preferred Stock issued or issuable upon the exercise of the warrants issued to Paramount Capital, Inc., the placement agent in connection with the offer and sale of the Series A Convertible Preferred Stock) shall be outstanding, the Corporation shall not, without the affirmative vote or consent of the holders of at least 66.67% of all outstanding Series A Convertible Preferred Stock voting separately as a class, (i) amend, alter or repeal any provision of the Certificate of Incorporation, as amended, or the Bylaws of the Corporation so as adversely to affect the relative rights, preferences, qualifications, limitations or restrictions of the Series A Convertible Preferred Stock, (ii) declare any dividend or distribution on the Common Stock or any other class or series of preferred stock or authorize the repurchase of any securities of the Corporation or (iii) authorize or issue, or increase the authorized amount of, any additional class or series of stock, or any security convertible into stock of such class or series, (A) ranking prior to, or on a parity with, the Series A Convertible Preferred Stock upon liquidation, dissolution or winding up of the Corporation or a sale of all or substantially all of the assets of the Corporation or (B) providing for the payment of any dividends or distributions. A class vote on the part of the Series A Convertible Preferred Stock shall, without limitation, specifically not be deemed to be required (except as otherwise required by law or resolution of the Corporation's Board of Directors) in connection with: (a) the authorization, issuance or increase in the authorized amount of Common Stock or of any shares of any other class or series of stock ranking junior to the Series A Convertible Preferred Stock in respect of distributions upon liquidation, dissolution or winding up of the Corporation;
(b) the authorization, issuance or increase in the amount of the Series A Convertible Preferred Stock or any bonds, mortgages, debentures or other obligations of the Corporation (other than bonds, mortgages, debentures or other obligations convertible into or exchangeable for or having option rights to purchase any shares of stock of the Corporation the authorization issuance or increase in amount of which would require the consent of the holders of the Series B Preferred Stock); or (c) any consolidation or merger of the Corporation with or into another corporation in which the Corporation is not the surviving entity, a sale or transfer of all or part of the Corporation's assets for cash, securities or other property, or a compulsory share exchange.

-9-

7. Outstanding Shares. For purposes of this Certificate of Designations, all shares of Series A Convertible Preferred Stock shall be deemed outstanding except (i) from the date, or the deemed date, of surrender of certificates evidencing shares of Series A Convertible Preferred Stock, all shares of Series A Convertible Preferred Stock converted into Common Stock, (ii) from the date of registration of transfer, all shares of Series A Convertible Preferred Stock held of record by the Corporation or any subsidiary of the Corporation and (iii) any and all shares of Series A Convertible Preferred Stock held in escrow prior to delivery of such stock by the Corporation to the initial beneficial owners thereof.

8. Status of Acquired Shares. Shares of Series A Convertible Preferred Stock received upon conversion pursuant to Section 4 or Section 5 or otherwise acquired by the Corporation will be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to class, and may thereafter be issued, but not as shares of Series A Convertible Preferred Stock.

9. Preemptive Rights. The Series A Convertible Preferred Stock is not entitled to any preemptive or subscription rights in respect of any securities of the Corporation.

10. No Amendment or Impairment. The Corporation shall not amend its Certificate of Incorporation or participate in any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, for the purpose of avoiding or seeking to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in carrying out all such action as may be reasonably necessary or appropriate in order to protect the conversion rights of the holders of the Series A Preferred Stock against impairment.

11. Severability of Provisions. Whenever possible, each provision hereof shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision hereof is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or otherwise adversely affecting the remaining provisions hereof. If a court of competent jurisdiction should determine that a provision hereof would be valid or enforceable if a period of time were extended or shortened or a particular percentage were increased or decreased, then such court may make such change as shall be necessary to render the provision in question effective and valid under applicable law.

BYLAWS

MicroBio Inc.
(a Delaware corporation)


ARTICLE I

STOCKHOLDERS

1. CERTIFICATES REPRESENTING STOCK. Certificates representing stock in the corporation shall be signed by, or in the name of, the corporation by the Chairman or Vice-Chairman of the Board of Directors, if any, or by the President or a Vice-President and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary of the corporation. Any or all the signatures on any such certificate may be a facsimile. In case any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent, or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he were such officer, transfer agent, or registrar at the date of issue.

Whenever the corporation shall be authorized to issue more than one class of stock or more than one series of any class of stock, and whenever the corporation shall issue any shares of its stock as partly paid stock, the certificates representing shares of any such class or series or of any such partly paid stock shall set forth thereon the statements prescribed by the General Corporation Law. Any restrictions on the transfer or registration of transfer of any shares of stock of any class or series shall be noted conspicuously on the certificate representing such shares.

The corporation may issue a new certificate of stock or uncertificated shares in place of any certificate theretofore issued by it, alleged to have been lost, stolen, or destroyed, and the Board of Directors may require the owner of the lost, stolen, or destroyed certificate, or his legal representative, to give the corporation a bond sufficient to indemnify the corporation against any claim that may be made against it on account of the alleged loss, theft, or destruction of any such certificate or the issuance of any such new certificate or uncertificated shares.

2. UNCERTIFICATED SHARES. Subject to any conditions imposed by the General Corporation Law, the Board of Directors of the corporation may provide by

-1-

resolution or resolutions that some or all of any or all classes or series of the stock of the corporation shall be uncertificated shares. Within a reasonable time after the issuance or transfer of any uncertificated shares, the corporation shall send to the registered owner thereof any written notice prescribed by the General Corporation Law.

3. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be required to, issue fractions of a share. If the corporation does not issue fractions of a share, it shall (1) arrange for the disposition of fractional interests by those entitled thereto, (2) pay in cash the fair value of fractions of a share as of the time when those entitled to receive such fractions are determined, or (3) issue scrip or warrants in registered form (either represented by a certificate or uncertificated) or bearer form (represented by a certificate) which shall entitle the holder to receive a full share upon the surrender of such scrip or warrants aggregating a full share. A certificate for a fractional share or an uncertificated fractional share shall, but scrip or warrants shall not unless otherwise provided therein, entitle the holder to exercise voting rights, to receive dividends thereon, and to participate in any of the assets of the corporation in the event of liquidation. The Board of Directors may cause scrip or warrants to be issued subject to the conditions that they shall become void if not exchanged for certificates representing the full shares or uncertificated full shares before a specified date, or subject to the conditions that the shares for which scrip or warrants are exchangeable may be sold by the corporation and the proceeds thereof distributed to the holders of scrip or warrants, or subject to any other conditions which the Board of Directors may impose.

4. STOCK TRANSFERS. Upon compliance with provisions restricting the transfer or registration of transfer of shares of stock, if any, transfers or registration of transfers of shares of stock of the corporation shall be made only on the stock ledger of the corporation by the registered holder thereof, or by his attorney thereunto authorized by power of attorney duly executed and filed with the Secretary of the corporation or with a transfer agent or a registrar, if any, and, in the case of shares represented by certificates, on surrender of the certificate or certificates for such shares of stock properly endorsed and the payment of all taxes due thereon.

5. RECORD DATE FOR STOCKHOLDERS. In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than sixty nor less than ten days before the date of such meeting. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of

-2-

stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting. In order that the corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date has been fixed by the Board of Directors, the record date for determining the stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required by the General Corporation Law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the corporation's registered office shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by the General Corporation Law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action. In order that the corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion, or exchange of stock, or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than sixty days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

6. MEANING OF CERTAIN TERMS. As used herein in respect of the right to notice of a meeting of stockholders or a waiver thereof or to participate or vote thereat or to consent or dissent in writing in lieu of a meeting, as the case may be, the term "share" or "shares" or "share of stock" or "shares of stock" or "stockholder" or "stockholders" refers to an outstanding share or shares of stock and to a holder or holders of record of outstanding shares of stock when the corporation is authorized to issue only one class of shares of stock, and said reference is also intended to include any outstanding share or shares of stock and any holder or holders of record of outstanding shares of stock of any class upon which or upon whom the certificate of incorporation confers such rights where there are two or more classes or series of shares of stock or upon which or upon whom the General Corporation Law confers such rights notwithstanding that the certificate or incorporation may provide for more than one class or series of shares of stock, one or more

-3-

of which are limited or denied such rights thereunder; provided, however, that no such right shall vest in the event of an increase or a decrease in the authorized number of shares of stock of any class or series which is otherwise denied voting rights under the provisions of the certificate of incorporation, except as any provision of law may otherwise require.

7. STOCKHOLDER MEETINGS.

-TIME. The annual meeting shall be held on the date and at the time fixed, from time to time, by the directors, provided, that the first annual meeting shall be held on a date within thirteen months after the organization of the corporation, and each successive annual meeting shall be held on a date within thirteen months after the date of the preceding annual meeting. A special meeting shall be held on the date and at the time fixed by the directors.

-PLACE. Annual meetings and special meetings shall be held at such place, within or without the State of Delaware, as the directors may, from time to time, fix. Whenever the directors shall fail to fix such place, the meeting shall be held at the registered office of the corporation in the State of Delaware.

-CALL. Annual meetings and special meetings may be called by the directors or by any officer instructed by the directors to call the meeting.

-NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall be given, stating the place, date, and hour of the meeting and stating the place within the city or other municipality or community at which the list of stockholders of the corporation may be examined. The notice of an annual meeting shall state that the meeting is called for the election of directors and for the transaction of other business which may properly come before the meeting, and shall (if any other action which could be taken at a special meeting is to be taken at such annual meeting) state the purpose or purposes. The notice of a special meeting shall in all instances state the purpose or purposes for which the meeting is called. The notice of any meeting shall also include, or be accompanied by, any additional statements, information, or documents prescribed by the General Corporation Law. Except as otherwise provided by the General Corporation Law, a copy of the notice of any meeting shall be given, personally or by mail, not less than ten days nor more than sixty days before the date of the meeting, unless the lapse of the prescribed period of time shall have been waived, and directed to each stockholder at his record address or at such other address which he may have furnished by request in writing to the Secretary of the corporation. Notice by mail shall be deemed to be given when deposited, with postage thereon prepaid, in the United States Mail. If a meeting is adjourned to another time, not more than thirty days hence, and/or to another place, and if an announcement of the adjourned time and/or place is made at the meeting, it shall not be necessary to give notice of the adjourned meeting unless the directors, after adjournment, fix a new record date for

-4-

the adjourned meeting. Notice need not be given to any stockholder who submits a written waiver of notice signed by him before or after the time stated therein. Attendance of a stockholder at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice.

-STOCKHOLDER LIST. The officer who has charge of the stock ledger of the corporation shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting, either at a place within the city or other municipality or community where the meeting is to be held, which place shall be specified in the notice of the meeting, or if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. The stock ledger shall be the only evidence as to who are the stockholders entitled to examine the stock ledger, the list required by this section or the books of the corporation, or to vote at any meeting of stockholders.

-CONDUCT OF MEETING. Meetings of the stockholders shall be presided over by one of the following officers in the order of seniority and if present and acting - the Chairman of the Board, if any, the Vice-Chairman of the Board, if any, the President, a Vice-President, or, if none of the foregoing is in office and present and acting, by a chairman to be chosen by the stockholders. The Secretary of the corporation, or in his absence, an Assistant Secretary, shall act as secretary of every meeting, but if neither the Secretary nor an Assistant Secretary is present the Chairman of the meeting shall appoint a secretary of the meeting.

-PROXY REPRESENTATION. Every stockholder may authorize another person or persons to act for him by proxy in all matters in which a stockholder is entitled to participate, whether by waiving notice of any meeting, voting or participating at a meeting, or expressing consent or dissent without a meeting. Every proxy must be signed by the stockholder or by his attorney-in-fact. No proxy shall be voted or acted upon after three years from its date unless such proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and, if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be

-5-

made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the corporation generally.

-INSPECTORS. The directors, in advance of any meeting, may, but need not, appoint one or more inspectors of election to act at the meeting or any adjournment thereof. If an inspector or inspectors are not appointed, the person presiding at the meeting may, but need not, appoint one or more inspectors. In case any person who may be appointed as an inspector fails to appear or act, the vacancy may be filled by appointment made by the directors in advance of the meeting or at the meeting by the person presiding thereat. Each inspector, if any, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspectors at such meeting with strict impartiality and according to the best of his ability. The inspectors, if any, shall determine the number of shares of stock outstanding and the voting power of each, the shares of stock represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots, or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots, or consents, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. On request of the person presiding at the meeting, the inspector or inspectors, if any, shall make a report in writing of any challenge, question, or matter determined by him or them and execute a certificate of any fact found by him or them. Except as otherwise required by subsection (e) of Section 231 of the General Corporation Law, the provisions of that Section shall not apply to the corporation.

-QUORUM. The holders of a majority of the outstanding shares of stock shall constitute a quorum at a meeting of stockholders for the transaction of any business. The stockholders present may adjourn the meeting despite the absence of a quorum.

-VOTING. Each share of stock shall entitle the holder thereof to one vote. Directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Any other action shall be authorized by a majority of the votes cast except where the General Corporation Law prescribes a different percentage of votes and/or a different exercise of voting power, and except as may be otherwise prescribed by the provisions of the certificate of incorporation and these Bylaws. In the election of directors, and for any other action, voting need not be by ballot.

8. STOCKHOLDER ACTION WITHOUT MEETINGS. Any action required by the General Corporation Law to be taken at any annual or special meeting of stockholders, or any action which may be taken at any annual or special meeting of stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be

-6-

necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing. Action taken pursuant to this paragraph shall be subject to the provisions of
Section 228 of the General Corporation Law.

ARTICLE II

DIRECTORS

1. FUNCTIONS AND DEFINITION. The business and affairs of the corporation shall be managed by or under the direction of the Board of Directors of the corporation.

Any director may resign at any time upon written notice to the corporation. Thereafter, directors who are elected at an annual meeting of stockholders, and directors who are elected in the interim to fill vacancies and newly created directorships, shall hold office until the next annual meeting of stockholders and until their successors are elected and qualified or until their earlier resignation or removal. Except as the General Corporation Law may otherwise require, in the interim between annual meetings of stockholders or of special meetings of stockholders called for the election of directors and/or for the removal of one or more directors and for the filling of any vacancy in that connection, newly created directorships and any vacancies in the Board of Directors, including unfilled vacancies resulting from the removal of directors for cause or without cause, may be filled by the vote of a majority of the remaining directors then in office, although less than a quorum, or by the sole remaining director.

SERIES A PREFERRED STOCK

of

ACUTE THERAPEUTICS, INC.

Pursuant to Section 151 of the

General Corporation Law of the State of Delaware

ACUTE THERAPEUTICS, INC., a corporation organized and existing under the laws of the State of Delaware (the "Corporation"), does hereby certify that, pursuant to the authority conferred on the Board of Directors of the Corporation by the Certificate of Incorporation of the Corporation and in accordance with
Section 151 of the General Corporation Law of the State of Delaware, the Board of Directors of the Corporation adopted the following resolution establishing a series of 600,000 shares of Preferred Stock of the Corporation designated as "Series A Preferred Stock":

RESOLVED, that pursuant to the authority conferred on the Board of Director of this Corporation by the Certificate of Incorporation a series of Preferred Stock, par value $.001 per share, of the Corporation is hereby established and created, and that the designation and number of shares therefor and the voting and other powers, preferences and relative, participating, optional or other rights of the shares of such series and the qualifications, limitations and restrictions thereof are as follows:


A. SERIES A PREFERRED STOCK.

The Series A Preferred Stock shall have the following rights, preferences, powers, privileges and restrictions, qualifications and limitations.

1. Dividends.

When and if the Board of Directors shall declare a dividend payable with respect to the then outstanding shares of Common Stock of the Corporation, the holders of the Series A Preferred Stock shall be entitled to the amount of dividends per share as would be payable on the largest number of whole shares of Common Stock into which each share of Series A Preferred Stock could then be converted pursuant to Section 4 hereof (such number to be determined as of the record date for the determination of holders of Common Stock entitled to receive such dividend).

2. Liquidation, Dissolution or Winding Up; Certain Mergers, Consolidations and Asset Sales.

(a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of shares of Series A Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its stockholders after and subject to the payment in full of all amounts required to be distributed to the holders of any other class or series of stock of the Corporation ranking on liquidation prior and in preference to the Series A Preferred Stock (collectively referred to as "Senior Preferred Stock"), but before any payment shall be made to the holders of Common Stock or any other class or series of stock ranking on liquidation junior to the Series A Preferred Stock (the Common Stock and any other class or series of stock ranking on liquidation junior to the Series A Preferred Stock being collectively referred to as "Junior Stock") by reason of their ownership thereof, an amount equal to $12.50 per share (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares), plus any dividends declared or accrued but unpaid thereon. If upon any such liquidation, dissolution or winding up of the Corporation the remaining assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series A Preferred Stock the full amount to which they shall be entitled, the holders of shares of Series A Preferred Stock and any class or series of stock ranking on liquidation on a parity with the Series A Preferred Stock shall share ratably in any distribution of the remaining assets and funds of the Corporation in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(b) After the payment of all preferential amounts required to be paid to the holders of Senior Preferred Stock, Series A Preferred Stock and any other class or series of stock of the Corporation ranking on liquidation on a parity with the Series A Preferred Stock, upon the dissolution, liquidation or winding up of the Corporation, the holders of shares of Junior Stock then outstanding shall be entitled to receive the remaining assets and funds of the Corporation available for distribution to its stockholders.

(c) The consolidation or merger of the Corporation into or with any other entity or entities or the consummation of any transaction or series of transactions which results in either (i) the exchange by the holders of outstanding shares of the Corporation of 50% or more of either (x) the then outstanding shares of Common Stock or (y) the combined voting power of the Corporation's then outstanding securities entitled to vote generally in the election of directors or other general matters, (ii) the holders of outstanding shares of the Corporation immediately prior to the consummation of such


transaction or transactions holding less than 50% of the outstanding securities of the resulting entity entitled to vote generally in the election of directors or other general matters (either of (i) and (ii) being hereinafter referred to as a "Change-in-Control Event") or (iii) the sale or transfer by the Corporation of all or substantially all its assets (a "Consolidation Event"), shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of the provisions of this Section 2. The consolidation or merger of the Corporation into or with any entity or entities which results in the exchange of outstanding shares of the Corporation for securities or other consideration issued or paid or caused to be issued or paid by any such entity or affiliate thereof which does not result in a Change-of-Control Event or a Consolidation Event shall not be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of the provisions of this
Section 2.

3. Voting.

(a) Each holder of outstanding shares of Series A Preferred Stock shall be entitled to the number of votes equal to the number of whole shares of Common Stock into which the shares of Series A Preferred Stock held by such holder are then convertible (as adjusted from time to time pursuant to Section 4 hereof), at each meeting of stockholders of the Corporation (and written actions of stockholders in lieu of meetings) with respect to any and all matters presented to the stockholders of the Corporation for their action or consideration. Except as provided by law, by the provisions of Subsection 3(b) below or by the provision establishing any other series of Preferred Stock, holders of Series A Preferred Stock shall vote together with the holders of Common Stock as a single class.

(b) The Corporation shall not (i) amend, alter or repeal the preferences, special rights or other powers of the Series A Preferred Stock so as to affect adversely such series, or (ii) increase the authorized number of shares of such series. In either case without the written consent or affirmative vote of the holders of a majority of the then outstanding shares of such series, given in writing or by vote at a meeting, commencing or voting (as the case may be) separately as a class. For this purpose, without limiting the generality of the foregoing, the authorization of any shares of capital stock with preference or priority over Series A Preferred Stock as to the right to receive either dividends or amounts distributable upon liquidation, dissolution or winding up of the Corporation shall be deemed to affect adversely such series, and the authorization of any shares of capital stock on a parity with such series as to the right to receive either dividends or amounts distributable upon liquidation, dissolution or winding up of the Corporation shall not be deemed to affect adversely such series.

4. Optional Conversion. The holders of the Series A Preferred Stock shall have conversion rights as follows (the "Conversion Rights"):

(a) Right to Convert. Each share of Series A Preferred Stock shall be convertible, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into one (1) fully paid and nonassessable share of Common Stock (the "Ratio"). The Ratio at which shares of Series A Preferred Stock may be converted into shares of Common Stock shall be subject to adjustment as provided below.

In the event of a liquidation of the Corporation, the Conversion Rights shall terminate at the close of business on the first full day preceding the date fixed for the payment of any amounts distributable on liquidation to the holders of Series A Preferred Stock.

(b) Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Series A Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the


Corporation shall pay cash equal to such fraction multiplied by the then fair market value of the Common Stock into which the Series A Preferred Stock is being converted, as determined in good faith by the Board of Directors.

(c) Mechanics of Conversion.

(i) In order for a holder of Series A Preferred Stock to convert shares of Series A Preferred Stock into shares of Common Stock, such holder shall surrender the certificate or certificates for such shares of Series A Preferred Stock, at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent), together with written notice that such holder elects to convert all or any number of the shares of the Series A Preferred Stock represented by such certificate or certificates. Such notice shall state such holder's name or the names of the nominees in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. If required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or his, her or its attorney duly authorized in writing. The date of receipt of such certificates and notice by the transfer agent (or by the Corporation if the Corporation serves as its own transfer agent) shall be the conversion date ("Conversion Date"). The Corporation shall, as soon as practical after the Conversion Date, issue and deliver at such office to such holder of Series A Preferred Stock, or to his, her or its nominees, a certificate or certificates for the number of shares of Common Stock, to which such holder shall be entitled, together with cash in lieu of any fraction of a share.

(ii) The Corporation shall at all times when the Series A Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Series A Preferred Stock, such number of its duly authorize shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Series A Preferred Stock.

(iii) Upon any such conversion, no adjustment to the Ratio shall be made for any declared or executed buy unpaid dividends on the Series A Preferred Stock surrendered for conversion or on the Common Stock delivered upon conversion.

(iv) All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares, including the rights, if any, to receive notices and to vote, shall immediately cease and terminate on the Conversion Date, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor and payment of any dividends declared or accrued but unpaid thereon. Any shares of Series A Preferred Stock so converted shall be retired and cancelled and shall not be redeemed, and the Corporation (without the need for stockholder action) may from time to time take such appropriate action as may be necessary to reduce the authorized Series A Preferred Stock accordingly.

(v) The Corporation shall pay any and all issue and other taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of shares of Series A Preferred Stock pursuant to this Section 4. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock in a name other than that in which the shares of Series A Preferred Stock so converted were registered, and no such issuance or delivery shall be made unless and until the person or


early requesting such issuance has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid.

(e) Adjustment for Stock Splits and Combinations. If the Corporation shall at any time or from time to time after October 21, (the "Original Issue Date") affect a subdivision of the outstanding Common Stock, the Ratio then in effect immediately before that subdivision shall be proportionately described. If the Corporation shall at any time or from time to time after the Original Issue Date of the Series A Preferred Stock combine the outstanding shares of Common Stock, the Ratio then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective.

(a) Adjustment for Certain Dividends and Distributions. In the event the Corporation at any time, or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Ratio for the Series A Preferred Stock then in effect shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Ratio for the Series A Preferred Stock then in effect by a fraction:

(1) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and

(2) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution;

provided, however; if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed thereafter, the Ratio for the Series A Preferred Stock shall be recomputed accordingly as of the close of business on such record date and thereafter the Ratio for the Series A Preferred Stock shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions.

(f) Adjustments for Other Dividends and Distributions. In the event the Corporation at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation other than shares of Common Stock, then and in each such event provision shall be made so that the holders of Series A Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the amount of securities of the Corporation that they would have received had the Series A Preferred Stock been converted into Common Stock on the date of such event and had thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under this paragraph with respect to the rights of the holders of Series A Preferred Stock.

(g) Adjustment for Reclassification, Exchange or Substitution. If the Common Stock issuable upon the conversion of the Series A Preferred Stock shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification, or otherwise (other than a subdivision or combination of shares or stock dividend provided for above, or a reorganization, merger, consolidation, or sale of assets provided for below), then and in each such event the holders of Series A Preferred Stock shall have the right thereafter to convert such share into the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification, or other change, by holders of the number of shares of Common Stock into which such shares of Series A Preferred Stock might have been converted immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein.

(h) Adjustment for Merger or Reorganization, etc. In case of any consolidation or merger of the Corporation with or into another corporation or the sale of all or substantially all of the assets of the Corporation to another corporation (other than a consolidation, merger or sale which is covered by Subsection 2(e)), each share of Series A Preferred Stock shall thereafter be convertible (or shall be converted into a security which shall be convertible) into the kind and amount of shares of stock or other securities or property to which a holder of the number of shares of Common Stock of the Corporation deliverable upon conversion of such Series A Preferred Stock would have been entitled upon such consolidation, merger or sale; and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors) shall be made in the application of the provisions in this Section 4 set forth with respect to the rights and interest thereafter of the holders of the Series A Preferred Stock, to the end that the provisions set forth in this Section 4 (including provisions with respect to changes in and other adjustments of the Ratio) shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the conversion of the Series A Preferred Stock.

(i) No Impairment. The Corporation will not, by amendment of its Restated Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock against impairment.

5. Status of Acquired Shares. All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares, including the rights, if any, to receive notices and to vote, shall immediately cease and terminate on the Conversion Date, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor and payment of any dividends declared but unpaid thereon. Any shares of Series A Preferred Stock so converted shall be retired and cancelled and shall not be released, and the Corporation (without the need for stockholder action) may from time to time take such appropriate action as may be necessary to reduce the authorized Series A Preferred Stock accordingly.

6. Preemptive Rights. The Series A Convertible Preferred Stock is not entitled to any preemptive or subscription rights in respect of any securities of the Corporation.

7. No Amendment or Impairment. The Corporation shall not amend its Certificate of Incorporation or participate in any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, for the purpose of avoiding or seeking to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will on all issues in good faith assist in carrying out all such action as may be reasonably necessary or appropriate in order to protect the conversion rights of the holders of the Series A Preferred Stock against impairment.

8. Invalidity of Provisions. Whenever possible, each provision hereof shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision hereof is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or otherwise adversely affecting the remaining provisions hereof. If a part of competent jurisdiction should determine that a provision hereof would be valid or enforceable if a period of time were extended or shortened or a particular percentage were improved or dissolved, then such officer may make such change as shall be necessary to render the provisions in question effective and valid under applicable law.

winding up of the Corporation, the holders of shares of Junior Stock then outstanding shall be entitled to receive the remaining assets and funds of the Corporation available for distribution to its stockholders.

(c) The consolidation or merger of the Corporation into or with any other entity or entities or the consummation of any transaction or series of transactions which results in either (i) the exchange by the holders of outstanding shares of the Corporation of 50% or more of either (x) the then outstanding shares of Common Stock or (y) the combined voting power of the Corporation's then outstanding securities entitled to vote generally in the election of directors or other general matters, (ii) the holders of outstanding shares of the Corporation immediately prior to the consummation of such transaction or transactions holding less than 50% of the outstanding securities of the resulting entity entitled to vote generally in the election of directors or other general matters (either of (i) and (ii) being hereinafter referred to as a "Change-in-Control Event") or (iii) the sale or transfer by the Corporation of all or substantially all its assets (a "Consolidation Event"), shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of the provisions of this Section 2. The consolidation or merger of the Corporation into or with any entity or entities which results in the exchange of outstanding shares of the Corporation for securities or other considerations issued or paid or caused to be issued or paid by any such entity or affiliate thereof which does not result in a Change- of-Control Event or a Consolidation Event shall not be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of the provisions of this Section 2.

3. Voting Rights Except as required by law, the Series B Preferred Stock shall not have any voting rights with respect to any matters presented to the stockholders of the Corporation for their action or consideration.

4. Mandatory Redemption

(a) The Corporation will, upon the first to occur of (i) the approval of the first New Drug Application filed by the Corporation relating to or incorporating the KL4-Surfactant approved by the United States Food and Drug Administration or (ii) the closing of an initial public offering of the Corporation's Common Stock (the "Mandatory Redemption Date"), redeem from each holder of shares of Series B Preferred Stock, at a price equal to $1000 per share, plus any dividends declared or accrued but unpaid thereon, subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares, all of the outstanding shares of Series B Preferred Stock held by such holder on the applicable Mandatory Redemption Date payable, at the option of the Corporation, either (1) in cash, or (2) if (and only if) the Corporation's Common Stock is publicly quoted on a national securities exchange or otherwise (as more fully described below), in shares of Common Stock valued at the Current Market Price. The "Current Market Price" of the Company's Common Stock shall be determined as follows: (a) with respect to an event under clause
(ii) above, the Current Market Price shall be price per share paid by the public in such initial public offering or (b) with respect to an event under clause (i) above the Current Market Price shall mean the average closing price for the Corporation's Common Stock for the twenty (20) consecutive business day period ending as of the date three (3) business days prior to the Mandatory Redemption Date whether or not the sale price of the Common Stock was reported on any business day on the trading day immediately preceding the date of such determination. The closing price shall be the reported sales price regular way, in each case

-3-

on the principal national securities exchange or the Nasdaq National Market System on which the shares of the Corporation's Common Stock are listed or admitted to trading, or if not listed or admitted to trading thereon, the average of the closing bid and asked prices of the Common Stock in the over-the-counter market as reported by Nasdaq or any comparable system, or if the Common Stock is not listed on Nasdaq or a comparable system, the average of the closing bid and asked prices on such day in the domestic over-the-counter market as reported on the NASD Electronic Bulletin Board, or, if not reported on such bulletin board, in the "pink-sheets" published by the National Quotation Bureau, Incorporated.

(b) If the funds of the Corporation legally available for redemption of Series B Preferred Stock on any Mandatory Redemption Date are insufficient to redeem the number of shares of Series B Preferred Stock required under this
Section 4 to be redeemed on such date, those funds which are legally available will be used to redeem the maximum possible number of such shares of Series B Preferred Stock ratably on the basis of the number of shares of Series B Preferred Stock which would be redeemed on such date if the funds of the Corporation legally available therefor had been sufficient to redeem all shares of Series B Preferred Stock required to be redeemed on such date. At any time thereafter when additional funds of the Corporation become legally available for the redemption of Series B Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of the shares which the Corporation was theretofore obligated to redeem, ratably on the basis set forth in the preceding sentence.

(c) The Corporation shall provide notice of any redemption of Series B Preferred Stock pursuant to this Section 4 specifying the time and place of redemption and the Mandatory Redemption Price, by first class or registered mail, postage prepaid, to each holder of record of Series B Preferred Stock at the address for such holder last shown on the records of the transfer agent therefor (or the records of the Corporation, if it serves as its own transfer agent), not more than 60 nor less than 30 days prior to the date on which such redemption is to be made. If less than all Series B Preferred Stock owned by such holder is then to be redeemed, the notice will also specify the number of shares which are to be redeemed. Upon mailing any such notice of redemption, the Corporation will become obligated to redeem at the time of redemption specified therein all Series B Preferred Stock specified therein.

(d) Unless there shall have been a default in payment of the Mandatory Redemption Price, no share of Series B Preferred Stock shall be entitled to any dividends declared after its Mandatory Redemption Date, and on such Mandatory Redemption Date all rights of the holder of such share as a stockholder of the Corporation by reason of the ownership of such share will cease, except the right to receive the Mandatory Redemption Price of such share, without interest, upon presentation and surrender of the certificate representing such share, and such share will not from and after such Mandatory Redemption Date be deemed to be outstanding.

(e) Any Series B Preferred Stock redeemed pursuant to this Section 4 will be cancelled and will not under any circumstances be reissued, sold or transferred and the Corporation may from time to time take such appropriate action as may be necessary to reduce the authorized Series B Preferred Stock accordingly.

-4-

5. No Conversion Rights. The Series B Preferred Stock shall have no rights of conversion in respect of any securities of the Corporation.

6. No Reissuance of Series B Preferred Stock. No share or shares of Series B Preferred Stock acquired by the Corporation by reason of redemption, purchase or otherwise shall be reissued, and all such shares shall be cancelled, retired and eliminated from the shares which the Corporation shall be authorized to issue.

7. Redemptive Rights. The Series B Preferred Stock is not entitled to any preemptive or subscription rights in respect of any securities of the Corporation.

8. Reorganizations and Recapitalizations. If at any time or from time to time there shall be a reorganization or recapitalization of the Common Stock, then, as a condition of such reorganization or recapitalization, provision shall be made so that the holders of the Series B Preferred Stock shall thereafter be entitled to receive in exchange for the Series B Preferred Stock the number of shares of stock or other securities or property of the corporation or otherwise, to which a holder of Common Stock deliverable upon redemption would have been entitled on such reorganization or recapitalization.

9. Notice of Record Date. In the event of any taking by the Corporation of a record of the holders of any class of securities for the purpose of determining the holder thereof who are entitled to receive any dividend or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, the corporation shall mail to each holder of Series B Preferred Stock, at least twenty (20) days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of any dividend (other than a cash dividend) or other distribution, any right to such dividend, distribution or right.

10. No Amendment or Impairment. The Corporation shall not amend its Certificate of Incorporation or participate in any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, for the purpose of avoiding or seeking to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in carrying out all such action as may be reasonably necessary or appropriate in order to protect the conversion rights of the holders of the Series B Preferred Stock against impairment.

11. Protective Provisions. So long as any shares of Series B Preferred Stock are outstanding, the Corporation shall not, without first obtaining the approval (by vote or written consent, as provided by law) by majority vote of the Board of Directors and of the holders of at least a majority of the outstanding shares of the Series B Preferred Stock:

(a) amend or repeal any provisions of the Corporation's Certificate Incorporation or Bylaws which in any manner adversely affects the holders of Series B Preferred Stock; or

-5-

(b) Alter or change the designations, powers, rights, preferences or privileges, or the qualifications. limitations or restrictions of the Series B Preferred Stock; or

(c) Increase the authorized number of shares of Series B Preferred Stock; or

(d) Authorize, create or issue any class or series of stock or any other securities convertible into equity securities of the corporation having a preference over, or being on a party with, the Series B Preferred Stock with respect to dividends, redemptions or upon liquidation or dissolution of the corporation; or

(e) Reclassify the shares of Common Stock or any other shares of any class or series of capital stock hereafter created junior to the Series B Preferred Stock into shares of any class or series of capital stock
(i) ranking either as to payment of dividends, distributions of assets or redemptions, prior to or on parity with the Series B Preferred Stock, or
(ii) which in any manner adversely affects the holders of Series B Preferred Stock.

12. Severability of Provisions. Whenever possible, each provision hereof shall be interpreted in a manner as to be effective and valid under applicable law, but if any provisions hereof is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or otherwise adversely affecting the remaining provisions hereof. If a court of competent jurisdiction should determine that a provision hereof would be valid or enforceable if a period of time were extended or shortened or a particular percentage were increased or decreased, then such court may make such change as shall be necessary to render the provision in question effective and valid under applicable law.

ARTICLE 1 - Stockholders

1.1 Place of Meeting. All meetings of stockholders shall be held at such place within or without the State of Delaware as may be designated from time to time by the Board of Directors or the President or, if not so designated, at the registered office of the corporation.

1.2 Annual Meeting. The annual meeting of stockholders for the election of directors and for the transaction of such other business as may properly be brought before the meeting shall be held on a date to be fixed by the Board of Directors or the President (which date shall not be a legal holiday in the place where the meeting is to be held) at the time and place to be fixed by the Board of Directors or the President and stated in the notice of the meeting. If no annual meeting is held in accordance with the foregoing provisions, the Board of Directors shall cause the meeting to be held as soon thereafter as convenient. If no annual meeting is held in accordance with the foregoing provisions, a special meeting may be held in lieu of the annual meeting, and any action taken at that special meeting shall have the same effect as if it had been taken at the annual meeting, and in such case all references in these By-Laws to the annual meeting of the stockholders shall be deemed to refer to such special meeting.

1.3 Special Meeting. Special meetings of stockholders may be called at any time by the President or by the Board of Directors. Business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of meeting.

1.4 Notice of Meetings. Except as otherwise provided by law, written notice of each meeting of stockholders, whether annual or special, shall be given not less than 10 nor more than 60 days before the date of the meeting to each stockholder entitled to vote at such meeting. The notices of all meetings shall state the place, date and hour of the meeting. The notice of a special meeting shall state, in addition, the purpose or purposes for which the meeting is called. If mailed, notice is given when deposited in the United States mail, postage prepaid, directed to the stockholder at his address as it appears on the records of the corporation.

1.5 Voting List. The officer who has charge of the stock ledger of the corporation shall prepare, at least 10 days before every meeting of stockholders, a complete


list of the stockholders entitled to vote at the meeting, arranged in alphabetical order and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, at a place within the city where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time of the meeting, and may be inspected by any stockholder who is present.

1.6 Quorum. Except as otherwise provided by law, the Certificate of Incorporation or these By-Laws, the holders of a majority of the shares of the capital stock of the corporation issued and outstanding and entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business.

1.7 Adjournments. Any meeting of stockholders may be adjourned to any other time and to any other place at which a meeting of stockholders may be held under these By-Laws by the stockholders present or represented at the meeting and entitled to vote, although less than a quorum, or, if no stockholder is present, by any officer entitled to preside at or to act as Secretary of such meeting. It shall not be necessary to notify any stockholder of any adjournment of less than 30 days if the time and place of the adjourned meeting are announced at the meeting at which adjournment is taken, unless after the adjournment a new record date is fixed for the adjourned meeting. At the adjourned meeting, the corporation may transact any business which might have been transacted at the original meeting.

1.8 Voting and Proxies. Each stockholder shall have one vote for each share of stock entitled to vote held of record by such stockholder and a proportionate vote for each fractional share so held, unless otherwise provided in the Certificate of Incorporation. Each stockholder of record entitled to vote at a meeting of stockholders, or to express consent or dissent to corporate action in writing without a meeting, may vote or express such consent or dissent in person or may authorize another person or persons to vote or act for him by written proxy executed by the stockholder or his authorized agent and delivered to the Secretary of the corporation. No such proxy shall be voted or acted upon after three years from the date of its execution, unless the proxy expressly provides for a longer period.

1.9 Action at Meeting. When a quorum is present at any meeting, the holders of shares of stock representing a majority of the votes cast on a matter (or if there are two or more classes of stock entitled to vote as separate classes, then in the case of each such class, the holders of shares of stock of that class representing a majority of the votes cast on a matter) shall decide any matter to be voted upon by the stockholders at such meeting, except when a different vote is required by express provision of law, the Certificate of Incorporation or these By-Laws. When a quorum is present at any meeting, any election by stockholders shall be determined by a plurality of the votes cast on the election.

-2-

1.10 Action without Meeting. Any action required or permitted to be taken at any annual or special meeting of stockholders of the corporation may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote on such action were present and voted. Prompt notice of the taking of corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing.

ARTICLE 2 - Directors

2.1 General Powers. The business and affairs of the corporation shall be managed by or under the direction of a Board of Directors, who may exercise all of the powers of the corporation except as otherwise provided by law or the Certificate of Incorporation. In the event of a vacancy in the Board of Directors, the remaining directors, except as otherwise provided by law, may exercise the powers of the full Board until the vacancy is filled.

2.2 Number; Election and Qualification. The number of directors which shall constitute the whole Board of Directors shall be determined by resolution of the stockholders or the Board of Directors, but in no event shall be less than one. The number of directors may be decreased at any time and from time to time either by the stockholders or by a majority of the directors then in office, but only to eliminate vacancies existing by reason of the death, resignation, removal or expiration of the term of one or more directors. The directors shall be elected at the annual meeting of stockholders by such stockholders as have the right to vote on such election. Directors need not be stockholders of the corporation.

2.3 Enlargement of the Board. The number of directors may be increased at any time and from time to time by the stockholders or by a majority of the directors then in office.

2.4 Tenure. Each director shall hold office until the next annual meeting and until his successor is elected and qualified, or until his earlier death, resignation or removal.

2.5 Vacancies. Unless and until filled by the stockholders, any vacancy in the Board of Directors, however occurring, including a vacancy resulting from an enlargement of the Board, may be filled by vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director. A director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in office, and a director chosen to fill a position resulting from an increase in the number of directors shall hold office until the next annual meeting of stockholders and until his successor is elected and qualified, or until his earlier death, resignation or removal.

-3-

2.6 Resignation. Any director may resign by delivering his written resignation to the corporation at its principal office or to the President or Secretary. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event.

2.7 Regular Meetings. Regular meetings of the Board of Directors may be held without notice at such time and place, either within or without the State of Delaware, as shall be determined from time to time by the Board of Directors; provided that any director who is absent when such a determination is made shall be given notice of the determination. A regular meeting of the Board of Directors may be held without notice immediately after and at the same place as the annual meeting of stockholders.

2.8 Special Meetings. Special meetings of the Board of Directors may be held at any time and place, within or without the State of Delaware, designated in a call by the Chairman of the Board, President, two or more directors, or by one director in the event that there is only a single director in office.

2.9 Notice of Special Meetings. Notice of any special meeting of directors shall be given to each director by the Secretary or by the officer or one of the directors calling the meeting. Notice shall be duly given to each director (i) by giving notice to such director in person or by telephone at least 48 hours in advance of the meeting, (ii) by sending a telegram or telex, or delivering written notice by hand, to his last known business or home address at least 48 hours in advance of the meeting, or (iii) by mailing written notice to his last known business or home address at least 72 hours in advance of the meeting. A notice or waiver of notice of a meeting of the Board of Directors need not specify the purposes of the meeting.

2.10 Meetings by Telephone Conference Calls. Directors or any members of any committee designated by the directors may participate in a meeting of the Board of Directors or such committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation by such means shall constitute presence in person at such meeting.

2.11 Quorum. A majority of the total number of the whole Board of Directors shall constitute a quorum at all meetings of the Board of Directors. In the event one or more of the directors shall be disqualified to vote at any meeting, then the required quorum shall be reduced by one for each such director so disqualified; provided, however, that in no case shall less than one-third (1/3) of the number so fixed constitute a quorum. In the absence of a quorum at any such meeting, a majority of the directors present may adjourn the meeting from time to time without further notice other than announcement at the meeting, until a quorum shall be present.

-4-

2.12 Action at Meeting. At any meeting of the Board of Directors at which a quorum is present, the vote of a majority of those present shall be sufficient to take any action, unless a different vote is specified by law, the Certificate of Incorporation or these By-Laws.

2.13 Action by Consent. Any action required or permitted to be taken at any meeting of the Board of Directors or of any committee of the Board of Directors may be taken without a meeting, if all members of the Board or committee, as the case may be, consent to the action in writing, and the written consents are filed with the minutes of proceedings of the Board or committee.

2.14 Removal. Except as otherwise provided by the General Corporation Law of Delaware, any one or more or all of the directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors, except that the directors elected by the holders of a particular class or series of stock may be removed without cause only by vote of the holders of a majority of the outstanding shares of such class or series.

2.15 Committees. The Board of Directors may, by resolution passed by a majority of the whole Board, designate one or more committees, each committee to consist of one or more of the directors of the corporation. The Board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members of the committee present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board of Directors and subject to the provisions of the General Corporation Law of the State of Delaware, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the corporation and may authorize the seal of the corporation to be affixed to all papers which may require it. Each such committee shall keep minutes and make such reports as the Board of Directors may from time to time request. Except as the Board of Directors may otherwise determine, any committee may make rules for the conduct of its business, but unless otherwise provided by the directors or in such rules, its business shall be conducted as nearly as possible in the same manner as is provided in these By-Laws for the Board of Directors.

2.16 Compensation of Directors. Directors may be paid such compensation for their services and such reimbursement for expenses of attendance at meetings as the Board of Directors may from time to time determine. No such payment shall preclude any director from serving the corporation or any of its parent or subsidiary corporations in any other capacity and receiving compensation for such service.

-5-

Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event.

Any officer may be removed at any time, with or without cause, by vote of a majority of the entire number of directors then in office.

Except as the Board of Directors may otherwise determine, no officer who resigns or is removed shall have any right to any compensation as an officer for any period following his resignation or removal, or any right to damages on account of such removal, whether his compensation be by the month or by the year or otherwise, unless such compensation is expressly provided in a duly authorized written agreement with the corporation.

3.6 Vacancies.

-9-

A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

ARTICLE 5 - Indemnification

The corporation may, to the fullest extent authorized under the laws of the State of Delaware, as those laws may be amended and supplemented from time to time, indemnify any director, officer, employee and/or agent made, or threatened to be made, a party to an action or proceeding, whether criminal, civil, administrative or investigative, by reason of being a director, officer and/or employee of the corporation or a predecessor corporation or, at the corporation's request, a director or officer of another corporation, provided, however, that the corporation shall indemnify any such agent in connection with a proceeding initiated by such agent only if such proceeding was authorized by the Board of Directors of the corporation. The indemnification provided for in this Article 5 shall: (i) not be deemed exclusive of any other rights to which those indemnified may be entitled under any bylaw, agreement or vote of stockholders or disinterested directors or otherwise, both as to action in their official capacities and as to action in another capacity while holding such office, (ii) continue as to a person who has ceased to be a director, officer, employee and/or agent, as the case may be, and (iii) inure to the benefit of the heirs, executors and administrators of such a person. The corporation's obligation to provide indemnification under this Article 5 shall be offset to the extent of any other source of indemnification or any otherwise applicable insurance coverage under a policy maintained by the corporation or any other person.

Expenses incurred by a director of the corporation in defending a civil or criminal action, suit or proceeding by reason of the fact that he is or was a director of the corporation (or was serving at the corporation's request as a director or officer of another corporation) shall be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized by relevant sections of the General Corporation Law of Delaware. Notwithstanding the foregoing, the corporation shall not be required to advance such expenses to an agent who is a party to an action, suit or proceeding brought by the corporation and approved by a majority of the Board of Directors of the corporation which alleges willful misappropriation of corporate assets by such agent, disclosure of confidential information in violation of such agent's fiduciary or contractual obligations to the corporation or any other willful and deliberate breach in bad faith of such agent's duty to the corporation or its stockholders.

The foregoing provisions of this Article 5 shall be deemed to be a contract between the corporation and each director who serves in such capacity at any time while this bylaw is in effect, and any repeal or modification thereof shall not affect any rights or obligations then

-10-

existing with respect to any state of facts then or theretofore existing or any action, suit or proceeding theretofore or thereafter brought based in whole or in part upon any such state of facts.

The Board of Directors in its discretion shall have power on behalf of the corporation to indemnify any person, other than a director, made a party to any action, suit or proceeding by reason of the fact that he, his testator or intestate, is or was an officer or employee of the corporation.

To assure indemnification under this Article 5 of all directors, officers and employees who are determined by the corporation or otherwise to be or to have been "fiduciaries" of any employee benefit plan of the corporation which may exist from time to time, Section 145 of the General Corporation Law of Delaware shall, for the purposes of this Article 5, be interpreted as follows:
an "other enterprise" shall be deemed to include such an employee benefit plan, including without limitation, any plan of the corporation which is governed by the Act of Congress entitled "Employee Retirement Income Security Act of 1974," as amended from time to time; the corporation shall be deemed to have requested a person to serve an employee benefit plan where the performance by such person of his duties to the corporation also imposes duties on, or otherwise involves services by, such person to the plan or participants or beneficiaries of the plan; excise taxes assessed on a person with respect to an employee benefit plan pursuant to such Act of Congress shall be deemed "fines. "

ARTICLE 6 - General Provisions

6.1 Fiscal Year. Except as from time to time otherwise designated by the Board of Directors, the fiscal year of the corporation shall end on the last day of December in each year.

6.2 Corporate Seal. The corporate seal shall be in such form as shall be approved by the Board of Directors.

6.3 Waiver of Notice. Whenever any notice whatsoever is required to be given by law, by the Certificate of Incorporation or by these By-Laws, a waiver of such notice either in writing signed by the person entitled to such notice or such person's duly authorized attorney, or by telegraph, cable or any other available method, whether before, at or after the time stated in such waiver, or the appearance of such person or persons at such meeting in person or by proxy, shall be deemed equivalent to such notice.

6.4 Voting of Securities. Except as the directors may otherwise designate, the President or Treasurer may waive notice of, and act as, or appoint any person or persons to act as, proxy or attorney-in-fact for this corporation (with or without power of substitution)

-11-

at, any meeting of stockholders or shareholders of any other corporation or organization, the securities of which may be held by this corporation.

6.5 Evidence of Authority. A certificate by the Secretary, or an Assistant Secretary, or a temporary Secretary, as to any action taken by the stockholders, directors, a committee or any officer or representative of the corporation shall as to all persons who rely on the certificate in good faith be conclusive evidence of such action.

6.6 Certificate of Incorporation. All references in these By-Laws to the Certificate of Incorporation shall be deemed to refer to the Certificate of Incorporation of the corporation, as amended and in effect from time to time.

6.7 Transactions with Interested Parties. No contract or transaction between the corporation and one or more of the directors or officers, or between the corporation and any other corporation, partnership, association, or other organization in which one or more of the directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board of Directors or a committee of the Board of Directors which authorizes the contract or transaction or solely because his or their votes are counted for such purpose, if:

(1) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum;

(2) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or

(3) The contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified, by the Board of Directors, a committee of the Board of Directors, or the stockholders.

Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction.

6.8 Severability. Any determination that any provision of these By-Laws is for any reason inapplicable, illegal or ineffective shall not affect or invalidate any other provision of these By-Laws.

-12-

6.9 Pronouns. All pronouns used in these By-Laws shall be deemed to refer to the masculine, feminine or neuter, singular or plural, as the identity of the person or persons may require.

ARTICLE 7 - Amendments

7.1 By the Board of Directors. These By-Laws may be altered, amended or repealed or new by-laws may be adopted by the affirmative vote of a majority of the directors present at any regular or special meeting of the Board of Directors at which a quorum is present.

7.2 By the Stockholders. These By-Laws may be altered, amended or repealed or new by-laws may be adopted by the affirmative vote of the holders of a majority of the shares of the capital stock of the corporation issued and outstanding and entitled to vote at any regular meeting of stockholders, or at any special meeting of stockholders, provided notice of such alteration, amendment, repeal or adoption of new by-laws shall have been stated in the notice of such special meeting.

WHEREAS, the Company and the Transferor have agreed that, simultaneous with the transfer to the Company of the Inventory and Equipment, the Transferor will grant to the Company an exclusive world-wide license, including the right to sublicense, for the KL4-Surfactant technology;

3. Representations and Warranties of Transferor or JJDC.

Transferor or JJDC hereby represents and warrants, as to itself only to the extent indicated below, to the Company that:

a. Authorization. Transferor or JJDC has full corporate power and authority to enter into and perform its obligations under this Agreement, the Registration Rights Agreement attached as Exhibit A hereto (the "Registration Rights Agreement") and the Co-Sale Agreement attached as Exhibit B hereto (the "Co-Sale Agreement"), and each such Agreement constitutes a valid and legally binding obligation of Transferor and/or JJDC, enforceable in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors' rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

e. Third Party Consents. No consent, approval, or authorization of any third party on the part of Transferor is required in connection with the transfer of the Inventory and Equipment as contemplated by this Agreement.

f. Investment Representations.

(i) Investment Intent. This Agreement is made with Transferor in reliance upon its representation to the Company, which by acceptance hereof Transferor confirms, that the Shares have been acquired with Transferor's own assets for investment for the account of its affiliate, JJDC, not as a nominee or agent, and not with a view to the sale or distribution of any part thereof, and that JJDC has no present intention of selling, granting participation in, or otherwise distributing the same. By executing this

2.


Agreement, JJDC represents that it does not have any contract, undertaking, agreement or arrangement with any person or entity to sell, transfer, or grant participation, to such person or entity or to any third person or entity, with respect to any of the Shares.

(2) Restricted Securities. JJDC understands that the Shares have not been registered under the Act, on the ground that the sale provided for in this Agreement is exempt from the registration requirements of the Act, and that the Company's reliance on such exemption is predicated on Transferor's and JJDC's representations set forth herein.

JJDC understands that if the Company does not register with the Securities and Exchange Commission pursuant to sections 12 or 15 of the Securities Exchange Act of 1934 or if a registration statement covering the Shares (or a filing pursuant to the exemption from registration under Regulation A of the Act) under the Act is not in effect when he or she desires to sell the Shares, JJDC may be required to hold the Shares for an indeterminate period. JJDC also acknowledges that it understands that any sale of the Securities that might be made by JJDC in reliance upon Rule 144 under the Act may be made only in limited amounts in accordance with the terms and conditions of that rule and that JJDC may not be able to sell the Shares at the time or in the amount JJDC so desires. JJDC is familiar with Rule 144 and understands that the Shares constitute "restricted securities" within the meaning of that Rule.

(3) Investment Experience. In connection with the investment representations made herein JJDC represents that it is able to fend for itself in the transactions contemplated by this Agreement, has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of his or her investment, has the ability to bear the economic risks of its investment and has been furnished with and has had access to such information as JJDC has requested and deems appropriate to its investment decision.

(4) Limitations on Disposition. JJDC agrees that in no event will it make a disposition of any of the Shares, unless and until (a) JJDC shall have notified the Company of the proposed disposition and shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition, and (b) JJDC shall have furnished the Company with an opinion of counsel reasonably satisfactory to the Company to the effect that (i) such disposition will not require registration of such Shares under the Act, or
(ii) that appropriate action necessary for compliance with the Act has been taken, or (c) the Company shall have waived, expressly and in writing, its rights under clauses (a) and (b) of this subparagraph. In addition, prior to any disposition of any of the Shares, the Company may require the transferee or assignee to provide in writing investment representations and its agreement to the market stand-off provisions hereof in a form acceptable to the Company. The restrictions on disposition imposed by this Section 3(f)(4) shall cease terminate as to the Shares when: (i) such securities shall have been effectively registered under the Act and sold by the holder thereof in accordance with such registration, or (ii) an opinion of

3.


the kind described in the second preceding sentence states that all future transfers of such securities by the holder thereof would be exempt from registration under the 1933 Act.

The Company shall not be required (i) to transfer on its books any Shares of the Company which shall have been sold or transferred in violation of any of the provisions set forth in this Agreement, or (ii) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares shall have been so transferred. Transferor shall, during the term of this Agreement, exercise all rights and privileges of a shareholder of the Company with respect to the Shares after the issuance, and prior to the repurchase, thereof.

g. Legends. All certificates representing any Shares of the Company subject to the provisions of this Agreement shall have endorsed thereon the following legends (except that such certificates shall not be required to bear such legend after a transfer thereof if the transfer was made in compliance with Rule 144 or pursuant to a registration statement or, if the opinion of counsel referred to above is issued and provides that such legend is not required in order to establish compliance with any provisions of the 1933 Act):

(1) "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN INVENTORY TRANSFER/STOCK PURCHASE AGREEMENT WHICH INCLUDES A MARKET STAND-OFF AGREEMENT ON THE SALE OF THE SECURITIES. COPIES OF THE AGREEMENTS MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION."

(2) "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SHARES UNDER THE SECURITIES ACT OF 1933, OR PURSUANT TO RULE 144 UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT."

The Company agrees that neither the Company nor anyone acting on its behalf will offer any of the Shares or any similar securities for issuance or sale to, or solicit any offer to acquire any of the same from, anyone so as to make the issuance and sale of the Shares subject to the registration requirements of Section 5 of the 1933 Act.

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to Shares held by JJDC until the end of such 180-day period.

b. during the term of this Agreement, not to consult on nonanionic polyether alcohol polymers for any other commercial, for-profit entity; or, for any other commercial for-profit entity whose primary business is the development of nonanionic polyether alcohol polymers; provided, however, that nothing in this section shall prevent CONSULTANT from consulting on nonanionic polyether alcohol polymers, for any other entity.

ARTICLE X - SURVIVAL

5

any termination or expiration hereof.

ARTICLE XI - INFORMATION OF OTHERS

Consultant shall not be limited from sharing or discussing any such information with regulatory affairs Consultants that shall be deemed an agent of Consultant or other members of the Company's Scientific Advisory Board.

ARTICLE XII - SEVERABILITY

Every provision of this Agreement is intended to be severable. If any term or provision hereof is deemed unlawful or invalid in any jurisdiction for any reason whatsoever, such unlawfulness or invalidity shall not affect the validity of the remainder of this Agreement or the enforceability of such term or provision in any other jurisdiction. To the extent that any such term or provision is held to be unlawful or invalid, the parties agree to reform such term or provision in such a way which will be enforceable in the jurisdiction to which such holding applies, and

6

which will reflect, as nearly as permissible, the intention of the parties.

ARTICLE XIII - MISCELLANEOUS

This Agreement may be executed in one or more counterparts, each of which, when so executed shall be deemed to be an original and all of which counterparts, taken together, shall constitute one and the same instrument.

Neither this Agreement nor any term hereof may be amended, modified, supplemented or waived save in a written instrument executed by each

Exhibit 10.4

Agreement No. 96-0155

STANDARD LICENSE AGREEMENT: DELUCA TECHNOLOGY

This Agreement is made effective the 6th day of September, 1996, by and between Wisconsin Alumni Research Foundation (hereinafter called "WARF"), a nonstock, nonprofit Wisconsin corporation, and Discovery Laboratories, Inc. (hereinafter called "Discovery"), a corporation organized and existing under the laws of Delaware;

WHEREAS, WARF owns certain inventions relating to processes for preparing Compounds and to certain intermediates in such processes, and WARF is willing to grant a license to Discovery with respect to Compounds under certain patents claiming such inventions, and Discovery desires such a license under such patents;

NOW THEREFORE, in consideration of the mutual covenants and agreements set forth below, the parties covenant and agree as follows:

Section 1. Definitions.

For the purpose of this Agreement, the Appendix A definitions shall apply.

Section 2. Grant.

A. License.

(i) Patent Licenses

(1) Exclusive License - Compound.

WARF hereby grants to Discovery an exclusive license under the Licensed Patents to make and use Compounds for the preparation of Products and to make, have made, use and sell Products in the Licensed Field and Licensed Territory.

(2) Exclusive License - Use.

WARF hereby grants to Discovery an exclusive license under the Use Patents to use the Compounds, to use and sell Products and practice the methods claimed by the Use Patents in the Licensed Field and Licensed Territory.

(3) Nonexclusive License - Process.

WARF hereby grants to Discovery a nonexclusive license to practice Processes of Licensed Patents and Ancillary Patents and to make, have made and use Ancillary Compounds, but only for the purpose of making Compounds and Products in the Licensed Field and Licensed Territory.

Page 1 of 26

(ii) Product Information License

(1) Nonexclusive License - Information.

WARF hereby grants to Discovery a nonexclusive license to use the Product Information to make Products in the Licensed Field and Licensed Territory and to obtain governmental approval of Products in the Licensed Field and Licensed Territory.

(2) Confidentiality.

Discovery agrees to maintain the Product Information in confidence in accordance with this Section 2A(ii)(2) both during and after the term of this Agreement. Discovery may disclose the Product Information to any governmental agency pursuant to an application for approval of a Product in the Licensed Field and Licensed Territory if the confidentiality of such Product Information is reasonably protected under the law or policy of such agency. The law and policies imposed by the United States FDA shall be deemed acceptable for the United States. Otherwise, only persons within Discovery's organization and consultants of Discovery who execute written confidentiality agreements shall be permitted access to the Product Information, and only on a need-to-know basis. Discovery may make copies of the Product Information, but all such copies shall be subject to the terms of this Agreement.

(3) Additional Product Information.

If Discovery requires any existing raw or other data that verifies or supports any of the Product Information (including raw data contained in laboratory notebooks and the like) with regard to any governmental approval process or if required by any governmental approval agency, WARF will use its best efforts to obtain such raw data from Sumitomo and/or Taisho upon Discovery's written request to WARF. WARF shall pay the actual cost of the translation and verification of the translation of such data. Within thirty (30) days after the receipt of a supported invoice regarding such payments, Discovery will reimburse WARF for all such payments, provided that the translation is requested or approved by Discovery. All additional data provided to Discovery under this Section 2A(ii)(3) shall be considered Product Information hereunder.

B. Sublicenses.

(i) Discovery may grant written, exclusive or nonexclusive sublicenses to third parties; however, WARF shall not have any direct enforcement obligations to any such sublicensees under Section 9. Any agreement granting a sublicense shall state that the sublicense is subject to the termination of this Agreement. Discovery shall have the same responsibility for the activities of any sublicensee as if the activities were directly those of Discovery.

(ii) In respect to sublicenses granted by Discovery under this
Section 2B, Discovery shall pay to WARF [***]. In addition if Discovery receives any fees, minimum royalties or other payments in consideration for any rights granted under a sublicense, and such payments are not based directly upon the amount or value of products sold by the sublicensee, (hereinafter defined as "Other Sublicensee Income") then Discovery shall pay to WARF [***] of such Other Sublicensee Income in the manner specified in Section 3F; provided, however, that other Sublicensee Income shall exclude the following, in relation to which no payments shall be due to WARF:

[***] Confidential treatment requested.

Page 2 of 26

(a) payments received by Discovery solely for performance of research and development including, but not limited to, milestone payments for achievement of objectives in research and development, but only to the extent that such payments cover the actual cost of the research and development work conducted by Discovery or cover the license fees due on the completion of certain development milestones by Discovery under Sections 3B and 3C hereof;

(b) Investments made by a sublicensee in either Discovery or one of its affiliates to the extent that such investments are made at current market value, including but not limited to, any payments or other consideration representing the current market value of shares in Discovery or any of its affiliates;

(c) Payments made to Discovery solely to the extent that they cover the actual costs of conducting clinical testing and other activities in connection with obtaining regulatory approvals for Products; or

(d) Reimbursed expenses of Discovery.

For purposes of Subsection (b) above, the "current market value" of the investment shall be determined as follows: (i) it shall be determined as at the earlier of (a) the date when the investment is made or (b) the day prior to the date when the investment is first publicly disclosed on the Dow Jones News Wire (the "Determination Date"); (ii) if there is no public market for Discovery's securities that are being purchased by the sublicensee, then the current market value shall be determined by Discovery's Board of Directors in good faith, and if WARF disputes such determination, the current market value shall be determined by an independent investment banker whose fees shall be shared by Discovery and WARF; (iii) if there is a public market for Discovery's securities that are being purchased by the sublicensee, then the current market value shall be determined using the average of the closing bid and asked prices of the securities in the Over-The-Counter Market Summary or the closing price quoted on any exchange on which the securities are listed as published in The Wall Street Journal for the ten (10) trading days prior to the Determination Date. Notwithstanding the foregoing, in the event the sublicensee is purchasing Discovery's securities in connection with Discovery's initial public offering of such securities, the current market value shall be determined using the offering price of such securities to the public in Discovery's initial public offering. Discovery shall not receive from sublicensees anything of value in lieu of cash payments in consideration for any sublicense under this Agreement without the express prior written permission of WARF.

C. Option.

WARF hereby grants Discovery an option to expand the Licensed Territory to include all countries of the world except Argentina, Spain, Portugal, Korea and Japan by paying the appropriate option fees on the schedule set forth in Section 3C of this Agreement.

[***] Confidential treatment requested.

Page 3 of 26

E. Grant Forward.

(i) To the extent permitted by applicable law, WARF hereby grants Discovery a nonexclusive license to make the Compounds under the claims of future patent applications, and patents which mature from any such applications, which are owned by WARF if the claimed inventions are new and useful processes for making the Compounds or Products. Discovery's rights under such inventions shall be limited to the practice thereof within the Licensed Field and Licensed Territory and shall be subject to the intervening rights of third parties that have funded the research under which the inventions were first conceived and/or made and to the rights of current licensees. WARF will promptly notify Discovery of any such invention by mailing a copy of the U.S. patent application, without claims, directed to such invention to:

Discovery Laboratories, Inc. Attn: Mr. Steve Kanzer 375 Park Avenue
New York, New York 10152

Such notification shall be given to Discovery promptly after WARF has filed the U.S. patent application.

(ii) Sixty (60) days after receipt by Discovery of such notification, and unless Discovery informs WARF in writing that it has elected otherwise, such new and useful invention(s) shall become a part of the Ancillary Patents hereunder. At any time more than two (2) years after receipt by Discovery of such notification, WARF may inquire of Discovery as to whether Discovery is in fact then actually using the added invention(s) to make Compounds. If Discovery is not doing so, WARF may, at its sole discretion, delete such invention(s) from Ancillary Patents.

Section 3. Consideration.

A. Development.

Discovery agrees to and warrants that: it has, or will obtain, the expertise necessary to independently evaluate the inventions of the Licensed Patents; it will establish and actively and diligently pursue the development plan (see Appendix H) to the end that the inventions of the Licensed Patents will be utilized to provide Products for sale in the retail market; and within one month following the end of each calendar quarter ending on March 31, June 30, September 30 and December 31 and until the date of first commercial sale of Products, it will supply WARF with a written Development Report. All development activities and strategies and all aspects of Products design and decisions to market and the like are entirely at the discretion of Discovery, and Discovery shall rely entirely on its own expertise with respect thereto. WARF's review of Discovery's development plan is solely to verify the existence of Discovery's commitment to development activity and to assure compliance with Discovery's obligations to utilize the inventions of the Licensed Patents for the marketplace, as set forth above. The development plan set forth on Appendix H represents the current plans for the development work to be carried out by Discovery. The parties recognize and agree that it will be necessary from time to time to revise the development plan to take account of changes in circumstances relating to the development work, and that the parties shall work together in good faith to determine mutually acceptable modifications to the development plan; provided, however, that such modifications shall only become effective once a written revised development plan is prepared and signed on behalf of both parties

E. Minimum Royalty.

Discovery further agrees to pay to WARF a minimum royalty of $100,000 per calendar year or part thereof during which this Agreement is in effect starting in calendar year 2002, against which any earned royalty paid for the same calendar year will be credited. The minimum royalty for a given year shall be due at the time payments are due for the calendar quarter ending on December 31. It is understood that the minimum royalties will apply on a calendar year basis, and that sales of Products requiring the payment of earned royalties made during a prior or subsequent calendar year shall have no effect on the annual minimum royalty due WARF for any given calendar year.

F. Accounting; Payments.

(i) Amounts owing to WARF under Sections 2B and 3D shall be paid on a quarterly basis, with such amounts due and received by WARF on or before the thirtieth day following the end of the calendar quarter ending on March 31, June 30, September 30 or December 31 in which such amounts were earned. The balance of any amounts which remain unpaid for more than thirty (30) days after they are due to WARF shall accrue interest until paid at the rate of the lesser of one percent (1%) per month or the maximum amount allowed under applicable law.

B. WARF MAKES NO REPRESENTATIONS, EXTENDS NO WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, AND ASSUMES NO RESPONSIBILITIES WHATSOEVER WITH RESPECT TO USE, SALE, OR OTHER DISPOSITION BY DISCOVERY, ITS SUBLICENSEE(S) OR THEIR VENDEES OR OTHER TRANSFEREES OF PRODUCTS INCORPORATING OR MADE BY USE OF INVENTIONS LICENSED UNDER THIS AGREEMENT.

C. If a royalty payment deficiency is determined, Discovery and its sublicensee(s) shall pay the royalty deficiency outstanding within thirty
(30) days of receiving written notice thereof, plus interest on outstanding amounts as described in Section 3F(i).

D. If a royalty payment deficiency for a calendar year exceeds five percent (5%) of the royalties paid for that year, then Discovery or its sublicensee(s) shall be responsible for paying WARF's out-of-pocket expenses incurred with respect to such review.

Section 6. Term; Termination.

A. The term of the license granted under this Agreement shall begin on the execution date and shall end on the Royalty Termination Date at which time Discovery shall have a paid-up license under this Agreement.

B. Discovery may terminate this Agreement at any time by giving at least ninety days' written and unambiguous notice of such termination to WARF. Such a notice shall be accompanied by a statement of the reasons for termination.

C. If Discovery at any time defaults in the timely payment of any monies due to WARF or the timely submission to WARF of any Development Report, fails to actively pursue the development plan, or commits any material breach of any other material covenant herein contained, and Discovery fails to remedy any such breach or default within ninety days after written notice thereof by WARF, WARF may, at its option, terminate this Agreement by giving notice of termination to Discovery.

D. Upon the termination of this Agreement, Discovery shall remain obligated to provide an accounting for and to pay royalties earned up to the date of the termination and any minimum royalties shall be prorated as of the date of termination by the number of days elapsed in the applicable calendar year.

Section 7. Assignability.

This Agreement may not be transferred or assigned by Discovery except with the prior written consent of WARF, which shall not be unreasonably withheld; provided that Discovery may assign this Agreement (i) to the purchaser of substantially all of Discovery's stock, assets or business pursuant to the transaction transferring such assets, and (ii) to an affiliate of Discovery (meaning any entity which controls, is controlled by or is under common control with Discovery), provided in each case that the assignee first agrees to assume all of Discovery's obligations and liabilities under this Agreement.

subsequent SALE of such LICENSED PRODUCT by other than LICENSEE, AFFILIATE or SUBLICENSEE shall be royalty free. In the case of transfers or SALES of any LICENSED PRODUCT between LICENSEE and an AFFILIATE or between AFFILIATES, LICENSEE and SUBLICENSEE, one and only one royalty shall be payable thereon and such royalty shall become payable upon the final SALE thereof to a third party other than LICENSEE, AFFILIATE or SUBLICENSEE.

4.5 For the purposes of reporting and making payments of earned royalties under this SUBLICENSE AGREEMENT, the manufacture, SALE or USE of LICENSED PRODUCTS by any AFFILIATE to which the license and rights shall have been extended shall be considered the manufacture, SALE or USE of such LICENSED PRODUCTS by LICENSEE and any such AFFILIATE may make the pertinent reports and royalty payments specified in Article 4 hereof directly to LICENSOR on behalf of LICENSEE; otherwise, such reports and payments on account of SALES or USES of LICENSED PRODUCTS by each AFFILIATE shall be made by LICENSEE; and, in any event, the SALES and USES of LICENSED PRODUCTS by each such AFFILIATE shall be separately shown in the reports to LICENSOR if such information is readily available to LICENSEE.

Said books and the supporting data shall be maintained and kept open at all reasonable times, for three (3) years following the end of the calendar year to which they pertain (and access shall not be denied thereafter, if reasonably available), to the inspection of an independent accountant retained by LICENSOR for the purpose of verifying LICENSEE's royalty statements, or LICENSEE's compliance in other respects with this SUBLICENSE AGREEMENT. Names of customers and other confidential information shall not be disclosed to LICENSOR by such independent accountant. Such

11

accountant shall be retained at LICENSOR's sole expense, unless during any such inspection a deficiency in payments to LICENSOR of five percent (5%) or more is determined to exist in which event LICENSEE shall within thirty
(30) days reimburse LICENSOR for the full expense of retaining such accountant, including but not limited to professional and administrative fees, travel and subsistence costs.

4.7 LICENSEE within ninety (90) days after the first day of January, April, July and October of each year shall deliver to LICENSOR a true and accurate report, giving such particulars of the LICENSED PRODUCTS SOLD by LICENSEE, AFFILIATES and royalty received from SUBLICENSEES during the preceding three (3) months ("Accounting Period") under this SUBLICENSE AGREEMENT as are pertinent to an accounting for royalty under this SUBLICENSE AGREEMENT. These shall include at least the following, separately stated as to the LICENSED PRODUCTS:

(i) the quantity of LICENSED PRODUCTS invoiced by LICENSEE or AFFILIATES during those three(3) months and the billings therefor;

(ii) the allowable deductions therefrom;

12

York Edition, for the day upon which the transfer of funds for the royalty payment is made. If the transfer or the conversion into United States Dollar equivalents in any such instance is not lawful or possible, the payment of such part of the royalties as is necessary shall be made by the deposit thereof, in the currency of the country where the sales were made on which the royalty was based, to the credit and account of LICENSOR or its nominee in any commercial bank or trust company of its choice located in that country, prompt notice of which shall be given by LICENSEE to LICENSOR.

4.9 In the event that any taxes, withholding or otherwise, are levied by any taxing authority in connection with accrual or payment of any royalties payable to LICENSOR under this SUBLICENSE AGREEMENT, LICENSEE or its AFFILIATES and/or SUBLICENSEES shall have the right to pay such taxes to the local tax authorities on behalf of LICENSOR (or, in the case of SUBLICENSEE SALES, on behalf of LICENSEE), and the payment to LICENSOR of the net amount due after reduction by the amount of such taxes, together with evidence of payment of such taxes, shall fully satisfy LICENSEE's royalty obligations under this SUBLICENSE AGREEMENT. LICENSEE agrees to make a good faith effort to obtain a refund of any such taxes for LICENSOR if LICENSOR informs LICENSEE that it believes such taxes have been improperly levied.

4.10 In the event that any payment required under this SUBLICENSE AGREEMENT shall be overdue, LICENSEE shall pay interest thereon at an annual rate of TWO percent (2%) over the United States Clearing Bank Base Lending Rate computed from the date when the payment became due; provided that if such rate shall be in excess of that allowed by applicable law, then the highest rate allowable shall apply. Payment shall be deemed to have been made when received by LICENSOR.

10.1 Pursuant to the SCRIPPS AGREEMENT, SCRIPPS agreed, with the advice of LICENSOR, to diligently prepare, file and prosecute the patent applications filed within the PATENT RIGHTS and LICENSOR agreed to reimburse SCRIPPS for the reasonable expenses associated therewith. LICENSOR will continue to ensure the SCRIPPS will file, maintain and prosecute the patents and patent applications in the PATENT RIGHTS, and to continue to reimburse SCRIPPS for patent expenses, including expenses associated with any interference or opposition proceeding, under the SCRIPPS AGREEMENT as LICENSOR considers appropriate. Furthermore, to the extent not barred by the passage of time, LICENSOR will continue to file, maintain and prosecute the ORTHO patents and patent applications within the PATENT RIGHTS in the jurisdiction listed in Appendix 4.

10.2 LICENSOR will advise, or ensure that SCRIPPS advises, LICENSEE of the status of all patent applications and patents within the PATENT RIGHTS. LICENSOR will provide or will ensure that SCRIPPS provides LICENSEE with copies of any patent applications or amendments or continuations-in-part that it or SCRIPPS proposes to file with the U.S. Patent and Trademark Office and shall give LICENSEE the opportunity, for a period of at least five (5) business days after receipt, to review and comment on such applications.

This letter will terminate upon the earlier of (i) the execution the Definitive Agreements, or (ii) 45 days from the date hereof in the event that the Definitive Agreements are not entered into. This letter shall not entitle either party to claim any rights pursuant to this letter in the event that the other party to this letter completes a license to KL4-Surfactant exclusive of the other after the expiration or termination of this letter.

The parties expressly agree in advance that any and all further agreements between them, including any amendments or modifications to this letter of intent, shall be required to be in writing and signed by both parties. Notwithstanding the preceding sentences of this paragraph, the provisions of this paragraph and Section 11 hereof are agreed to be fully binding on the parties upon the execution of this Letter of Intent.

Dear Sirs:

1. This is to confirm our understanding that Paramount Capital, Inc. ("Paramount") has been engaged as financial advisor of Discovery Laboratories, Inc. (the "Company") for an initial period of twenty-four (24) months commencing on the date hereof (as extended pursuant to Paragraph 10 hereto, or by mutual agreement of the parties hereto, the "Term").

2. The Company will pay Paramount a non-refundable retainer fee for Paramount's services hereunder of $4,000 per month for twenty-four (24) months, which such non-refundable retainer fee shall be payable in full in the amount of $96,000 as of the date hereof.

The Company also agrees to pay in cash all reasonable out-of-pocket expenses incurred by Paramount in providing its services hereunder, including fees and disbursements of Paramount's counsel, such expenses to be paid upon submission of a bill or bills by Paramount from time to time. However, any single expense over $500 for any month will require the prior written approval of the Company. Fees and expenses of consultants or experts shall not be included unless approved by the Company.

3. Upon the Closing of each Investment (as defined below) during the Term or during the twelve-month period following the expiration or earlier termination of the Term, the Company shall pay to Paramount a fee in an amount equal to 9% of the aggregate value of such Investment and shall issue to Paramount warrants to purchase an amount of securities equal to 10% of the securities sold as part of such Investment at an exercise price of 110% of the price of such securities, exercisable until five years from the date of issuance of such warrants. For the purposes of this Agreement, an Investment shall be any purchase of securities of the Company which is made during the Term or during the twelve-month period following the expiration of the Term by an investor first introduced to the Company by or through Paramount during or prior to the Term.

4. (a) If the Company enters into an agreement with a party first introduced to the Company by or through Paramount during or prior to the Term pursuant to which the Company consummates a sale, merger, consolidation, tender offer, business combination or similar transaction involving a majority of the business assets or stock of the Company in which the Company is not the surviving entity (a "Sale") during the Term, or during the twelve-month


period following the expiration of such Term, then the Company shall pay Paramount a fee equal to 7% of the aggregate consideration paid to the Company by the acquiror, such fee to be payable in cash simultaneously with the closing of such Sale. With the exception of Acquiror Future Payments in which case such fees are to be payable at such time, and only if, the Company receives such Acquiror Future Payments.

(b) If the Company enters into an agreement with a party first introduced to the Company by or through Paramount during or prior to the Term pursuant to which the Company consummates a transaction wherein the Company acquires all or substantially all of the business assets or stock of another entity in which the Company is the surviving entity (an "Acquisition") during the Term, or during the twelve-month period following the expiration of such Term, then the Company shall pay Paramount a fee equal to 7% of the aggregate consideration paid by the Company to the entity acquired, such fee to be payable in cash simultaneously with the closing of such Acquisition. With the exception of Acquiror Future Payments in which case such fees are to be payable at such time, and only if, the Company receives such Acquiror Future Payments.

(c) For purposes of calculating Paramount's fee under this Paragraph 4, the aggregate consideration paid with respect to the business, assets or stock of the Company shall be equal to the total of all cash, securities and/or other assets paid for such business, assets or stock by the acquiror. Aggregate consideration shall also include: (a) any commercial bank or similar indebtedness of the Company that is repaid or for which the responsibility to pay is assumed by the acquiror in connection with such transaction, (b) the greater of the stated value or the liquidation value of preferred stock of the Company that is assumed or acquired by the acquiror that is not converted into common stock upon the consummation of such transaction, and (c) future payments for which the acquiror is obligated either absolutely or upon the attainment of milestone or financial results ("Acquiror Future Payments"). In the event a Sale of the Company or an Acquisition by the Company is consummated through a multiple-step transaction wherein the acquiror is not obligated either absolutely or upon the attainment of milestones or financial results to make future payments to further increase the acquiror's ownership in the Company (the "Multiple-Step Payments"), the Company agrees to pay Paramount a fee on such Multiple-Step Payments, and such fee shall be calculated pursuant to this Paragraph 4. Such fee shall be payable when such Multiple-Step Payments are made and shall be in addition to the fee paid to Paramount in the first step of such transaction.

5. If the Company enters into an agreement with a party first introduced to the Company by or through Paramount during or prior to the Term pursuant to which the Company consummates a Strategic Alliance(s) (as defined below) during the Term, or during the twelve-month period following the expiration of such Term, then the Company shall pay Paramount a fee equal to 6% of the present value of the Aggregate Consideration (as defined below) to be received by the Company, its shareholders or employees in each such transaction; such fee to be payable in cash simultaneously with the closing of each such transaction. With the exception of payments received by the Company after closing of such transaction as in Paragraphs 5(c) and

2

5(d) below, in which case such fees are to be payable at such time, and only if, the Company receives such payments. For the purpose of calculating Paramount's fee under this Paragraph 5, Aggregate Consideration shall include, but not be limited to: (a) all payments made at closing for equity securities, equity security rights or similar rights, (b) technology access fees or similar upfront payments, (c) other future payments, including, without limitation, licensing fees, royalties and deferred technology access fees, to be made to the Company or its employees for which the Strategic Alliance partner(s) or other counter party (each a "Partner") is obligated either absolutely, upon the attainment of milestones or on a percentage or royalty basis, (d) funding provided, arranged or introduced by the Partner (through reimbursement or otherwise) relative to research and development, testing, clinical trials and related expenditures, whether such work is performed, subcontracted or managed by the Company or the Partner and (e) the repayment or assumption by the Partner of obligations of the Company, including indebtness for money borrowed or amounts owed by the Company to inventors or owners of technology. It is further understood that Aggregate Consideration shall not be reduced by the amount of the fee due Paramount hereunder.

Such securities which are traded over-the-counter shall be valued at the mean between the latest bid and asked prices prior to date.

6. If Paramount introduces the Company to a potential product, process or technology which is subsequently licensed or otherwise acquired by the Company, the Company and Paramount shall negotiate in good-faith a fee for such introduction provided in no event shall be such fee less than $120,000.

7. In the event that the Company, its directors or management initiate any discussions with a third party in furtherance of any Sale, Acquisition, Investment or Strategic Alliance or receive any meaningful inquiry or are aware of the interest if any third party concerning a Sale, Acquisition, Investment or Strategic Alliance which is the subject of this Agreement, they will promptly inform Paramount of the party and its interest and, subject to Paragraph 8, if applicable, Paramount will undertake to provide its services contemplated hereunder.

9. All non-public information given to Paramount by the Company will be treated by Paramount as confidential. In this regard, Paramount agrees to enter into such confidentiality agreements which may be reasonably requested by the Company. Paramount may rely, without independent verification, on the accuracy and completeness of any information furnished to Paramount by the Company.

10. In the event that Paramount becomes involved in any capacity in any action, proceeding, investigation or inquiry in connection with any matter referred to in this Agreement or arising out of the matters contemplated by this Agreement, the Company will reimburse Paramount for its legal and other expenses (including the cost of any investigation and preparation) as they are incurred by Paramount in connection therewith.

The foregoing agreement shall be in addition to any rights that any Indemnitees may have at common law or otherwise.

11. The Term of this Agreement shall be renewed for consecutive six month periods upon the execution of a written agreement by both parties to extend such Term and may be terminated by Paramount Capital, Inc. at any time with or without notice; provided, however, regardless of any termination, the right to reimbursement of all expenses incurred by Paramount contained in Paragraph 2, the rights to compensation contained in Paragraphs 3, 4 and 5 and to indemnity and reimbursement contained in Paragraph 10 shall survive.

12. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of law.

13. This Agreement shall be binding upon Paramount and the Company and the successors and assigns thereof. The Company shall not assign or sell all or substantially all of the Company's business and/or assets without first requiring in writing that such assignee or successor is bound by the provisions of this Agreement.

CERTIFICATES OF ANALYSIS AND MANUFACTURING COMPLIANCE

4.1 CERTIFICATES OF ANALYSIS: COOK shall test, or cause to be tested, in accordance with the Specifications, each batch of the Drug Product manufactured pursuant to this Agreement before delivery to CLIENT. A certificate of analysis for each batch delivered shall set forth the items tested, specifications, and test results. COOK shall also indicate on the certificate of analysis that all batch production and control records have been reviewed and approved by the appropriate quality control unit. COOK shall send, or cause to be sent, such certificates to CLIENT prior to the shipment of the Drug Product. CLIENT shall test, or cause to be tested, for final release, each batch of the Drug Product as meeting the Specifications. As required by the FDA (see Paragraph 5.2 below), CLIENT shall assume full responsibility for final release of each lot of the Drug Product.

4.2 MANUFACTURING COMPLIANCE: COOK shall advise CLIENT immediately if an authorized agent of any regulatory body visits COOK's manufacturing facility and makes an inquiry regarding COOK's method of manufacture of the Drug Product for CLIENT.

WARRANTIES

5.1 CONFORMITY WITH SPECIFICATIONS: COOK warrants that, at the time of manufacture, the Drug Product is prepared and tested in accordance with the Specifications, including cGMP. If the drug product does not meet specifications, and the reason being solely due to COOK's performance, then CLIENT will not be billed for the batch. Because of individual biological differences, no product is 100% effective under all circumstances. In addition, because COOK has no control of the conditions under which the Drug Product is used, the diagnosis of the patient before or after treatment with the Drug Product, the method of use or administration of the Drug Product, and handling of the Drug Product after it leaves COOK's possession, COOK does not warrant either a good effect, or against an ill effect, following the use of the Drug Product. The foregoing warranty is exclusive and in lieu of all other warranties either written, oral, or implied. THERE ARE NO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. No representative of COOK may change any of the foregoing warranties and CLIENT accepts the Drug Product subject to all terms hereof.

5.2 COMPLIANCE: Client assumes responsibility for all contact with the FDA and other regulatory bodies, pertaining specifically to Drug Product.

DRUG PRODUCT STOCK RECOVERY

6.1 DRUG PRODUCT STOCK RECOVERY: In the event CLIENT reasonably determines that the Drug Product should be recovered because the Drug Product does not conform to Specifications, the parties shall take all appropriate corrective actions. In no event, however, shall COOK have responsibility for regulatory compliance in connection with any recovery, except to the extent and under the circumstances set forth in the Manual or as required by law. All costs and expenses incurred in connection with such recovery shall be the responsibility of CLIENT unless caused solely by the negligence of COOK. In no event shall COOK have any liability for consequential damages incurred by CLIENT which arise out of, or in connection with, any Drug Product recovery.

FORCE MAJEURE; FAILURE TO SUPPLY

7.1 FORCE MAJEURE EVENTS: failure of either party to perform under this agreement (except the obligation to make payments) shall not subject such party to any liability to the other if such failure is caused by acts such as, but not limited to, acts of God, fire, explosion, flood, drought, war, riot, sabotage, embargo, strikes or other labor trouble, compliance with any order or regulation of any government entity, or by any cause beyond the reasonable control of the parties, whether or not foreseeable, provided that written notice of such event is promptly given to the other party.

7.2 FAILURE TO SUPPLY: If COOK fails to supply all or any material part of the Drug Product ordered by CLIENT, CLIENT may require COOK to supply the undelivered Drug Product or a lesser quantity at a future date agreed upon by CLIENT. The provisions of this Paragraph 7.2 shall be without prejudice to CLIENT's rights under paragraph 3.2 and remedies provided for thereunder.

IMPROVEMENTS

8.1 CHANGES BY CLIENT: If CLIENT requests a change to the Drug Product Specifications and COOK agrees that such change is feasible with regard to the manufacture of the Drug Product, such change shall be incorporated within the Specifications pursuant to a written amendment to this Agreement. The price of the Drug Product shall be adjusted for such change, and CLIENT shall pay COOK the costs associated with such change, including any development work, if necessary, based upon COOK's then-prevailing development rates. Such prices and costs shall be set forth in a written amendment to this Agreement. It is the responsibility of CLIENT to ensure that proper regulatory agencies approve the suggested changes.

8.2 CHANGES BY COOK: COOK agrees that any changes developed by COOK which may be incorporated into the Drug Product shall be set forth in a written amendment to this Agreement prior to such incorporation and approved by CLIENT in writing. At the time of such incorporation, such changes shall become part of the Specifications. It is the responsibility of CLIENT to ensure that proper regulatory agencies approve the suggested changes.

CONFIDENTIALITY

9.1 This Agreement, by reference, incorporates the Confidentiality Agreement signed by CLIENT and COOK on January 3, 1996, and is made a part hereof as though fully set forth herein.

9.2 Any invention made, conceived or reduced to practice by COOK in connection with the performance of the obligations under this Agreement, during the term of this Agreement or thereafter, whether derived from COOK or CLIENT, shall be considered confidential information and shall be the exclusive property of COOK; provided, however, that any invention made, conceived of, or reduced to practice during the Term of this Agreement, of (a) a pharmaceutical product with the same composition as the Drug Product, or (b) an improvement to the Drug Product, shall be the exclusive property of CLIENT. Each party, in its sole discretion, may file for patent protection of its invention as set forth above in its own name, and the other party, upon request by the owner, shall promptly sign and deliver any and all documents or information necessary for the securing of such invention in any country as determined by the owner.

9.3 The parties agree that contents of this Agreement shall not be disclosed to any third party except (i) the controlling companies of the parties, (ii) the companies controlled by the parties, and (iii) governmental regulatory agencies, including, but not limited to, environmental protection authorities, without prior written consent of the other party.

SCHEDULE II

MANUFACTURING PROJECT MANUAL

The policies and procedures outlined herein have been reviewed and will be adhered to in the manufacturing and/or finishing of the Drug Product pursuant to the Clinical Product Development Agreement (the "Agreement").

I. POLICY:

COOK's policy is to assure that the Drug Product manufactured and/or packaged for CLIENT will be processed under a total quality control system which ensures that the Drug Product will meet all warranties set forth in Section 5.1 of the Agreement.

II. PURPOSE:

The purpose of this Manual is to address and delineate the responsibilities between COOK and CLIENT and to provide a vehicle for implementation of the policy stated above.

III. SCOPE:

This Manual applies to all contract manufacturing activities for which COOK has manufacturing and/or finishing responsibility as set forth below.

RAW MATERIALS

All raw materials are defined by the Specifications outlined in Attachment I hereto which is made a part hereof by reference. An Approved Vendor List shall be jointly developed and approved by COOK and by CLIENT for the supply of these raw materials. The Approved Vendor List shall contain, but not be limited to, the following information:

Cook Imaging Corporation Development Agreement- 129; 1/8/97-02

14

CLIENT shall supply to COOK, in a timely manner, all Bulk Drug Substance necessary to satisfy COOK's obligations under the Agreement. At some point, CLIENT wishes for COOK to supply the excipients, namely Palmitic Acid, DPPC, and POPG. When this occurs, a price will be negotiated and agreed to jointly by both parties.

COOK will use standard operating procedures which define the sampling methodology and the analytical methods used to assure that the raw materials meet the Specifications.

Upon such termination of this Agreement, the parties shall continue to abide by their non-disclosure obligations as described in Section 6.1 and each party hereto shall fulfill any other obligations incurred prior to such termination. Any such termination of this Agreement shall not constitute the termination of any license or any other agreements between the parties which are then in effect except as expressly provided therein.

8.1 Assignment. This Agreement may not be assigned by either party without the prior written consent of the other party except to a successor in interest to all or substantially all of the business assets of assigning party, whether by way of a merger, consolidation, sale of all or substantially all of the assigning party's assets, change of control or similar transaction.

8.2 Binding Upon Successors and Assigns. Subject to the limitations on assignment set forth herein, this Agreement shall be binding upon and inure to the benefit of any successors in interest and assigns of Scripps and Optionee. Any such successor to or assignee of a party's interest shall expressly assume in writing the performance of all the terms and conditions of this Agreement to be performed by such party.

9. GENERAL PROVISIONS.

9.1 Independent Contractors. The relationship between Scripps and Optionee is that of independent contractors. Scripps and Optionee are not joint venturers, partners, principal and agent, master and servant, employer or employee, and have no other relationship other than independent contracting parties. Scripps and Optionee shall have no power to bind or obligate each other in any manner, other than as is expressly set forth in this Agreement.

9.2 Arbitration. Any controversy or claim arising out of or relating to this Agreement, or the breach thereof, shall be settled by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association ("AAA"), and the procedures set forth below. In the event of any inconsistency between the Rules of AAA and the procedures set forth below, the procedures set forth below shall control. Judgment upon the award rendered by the arbitrators may be enforced in any court having jurisdiction thereof.

9.2.1 Location. The location of the arbitration shall be in the City of Philadelphia.

9.2.2 Selection Arbitrators. The arbitration shall be conducted by a panel of three neutral arbitrators who are independent and disinterested with respect to the parties, this Agreement, and the outcome of the arbitration. Each party shall appoint one neutral arbitrator, and these two arbitrators so selected by the parties shall then select the third arbitrator. If one party has given written notice to the other party as to the

10

identity of the arbitrator appointed by the party, and the party thereafter makes a written demand on the other party to appoint its designated arbitrator within the next ten days, and the other party fails to appoint its designated arbitrator within ten days after receiving said written demand, then the arbitrator who has already been designated shall appoint the other two arbitrators.

9.2.3 Discovery. Unless the parties mutually agree in writing to some additional and specific pre-hearing discovery, the only pre-hearing discovery shall be (a) reasonably limited production of relevant and non-privileged documents, and (b) the identification of witnesses to be called at the hearing, which identification shall give the witness's name, general qualifications and position, and a brief statement as to the general scope of the testimony to be given by the witness. The arbitrators shall decide any disputes and shall control the process concerning these pre-hearing discovery matters. Pursuant to the Rules of AAA, the parties may subpoena witnesses and documents for presentation at the hearing.

9.2.4 Case Management. Prompt resolution of any dispute is important to both parties; and the parties agree that the arbitration of any dispute shall be conducted expeditiously. The arbitrators are instructed and directed to assume case management initiative and control over the arbitration process (including scheduling of events, pre-hearing discovery and activities, and the conduct of the hearing), in order to complete the arbitration as expeditiously as is reasonably practical for obtaining a just resolution of the dispute.

9.2.5 Remedies. The arbitrators may grant any legal or equitable remedy or relief that the arbitrators deem just and equitable, to the same extent that remedies or relief could be granted by a state or federal court, provided however, that no punitive damages may be awarded. No court action may be maintained seeking punitive damages. The decision of any two of the three arbitrators appointed shall be binding upon the parties.

9.2.6 Expenses. The expenses of the arbitration, including the arbitrators' fees, expert witness fees, and attorney's fees, may be awarded to the prevailing party, in the discretion of the arbitrators, or may be apportioned between the parties in any manner deemed appropriate by the arbitrators. Unless and until the arbitrators decide that one party is to pay for all (or a share) of such expenses, both parties shall share equally in the payment of the arbitrators' fees as and when billed by the arbitrators.

9.2.7 Confidentiality. Except as set forth below, the parties shall keep confidential the fact of the arbitration, the dispute being arbitrated, and the decision of the arbitrators. Notwithstanding the foregoing, the parties may disclose information about the arbitration to persons who have a need to know, such as directors, trustees, management

11

employees, witnesses, experts, investors, attorneys, lenders, insurers, and others who may be directly affected. Additionally, if a party has stock which is publicly traded, the party may make such disclosures as are required by applicable securities laws. Further, if a party is expressly asked by a third party about the dispute or the arbitration, the party may disclose and acknowledge in general and limited terms that there is a dispute with the other party which is being (or has been) arbitrated. Once the arbitration award has become final, if the arbitration award is not promptly satisfied, then these confidentiality provisions shall no longer be applicable.

9.3 Entire Agreement; Modification. This Agreement sets forth the entire agreement and understanding between the parties as to the subject matter hereof. There shall be no amendments or modifications to this Agreement, except by a written document which is signed by both parties.

9.4 California Law. This Agreement shall be construed and enforced in accordance with the laws of the State of California.

9.5 Headings. The headings for each article and section in this Agreement have been inserted for the convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular article or section.

9.6 Severability. Should any one or more of the provisions of this Agreement be held invalid or unenforceable by a court of competent jurisdiction, it shall be considered severed from this Agreement and shall not serve to invalidate the remaining provisions thereof. The parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by them when entering this Agreement may be realized.

9.7 No Waiver. Any delay in enforcing a party's rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such party's rights to the future enforcement of its rights under this Agreement, excepting only as to an express written and signed waiver as to a particular matter for a particular period of time.

9.8 Attorneys' Fees. In the event of a dispute among the parties hereto or in the event of any default hereunder, the party prevailing in the resolution of any such dispute or default shall be entitled to recover its reasonable attorneys' fees and other costs incurred in connection with resolving such dispute or default.

9.9 Notices. Any notices required by this Agreement shall be in writing, shall specifically refer to this Agreement and shall be sent by registered or certified airmail, postage prepaid, or by telefax, telex or cable, charges prepaid, or by overnight

2.6 Sublicense. Licensee shall have the sole and exclusive right to grant sublicenses to any party with respect to the rights conferred upon Licensee under this Agreement, provided, however, that any such sublicense shall be subject in all respects to the restrictions, exceptions, royalty obligations, reports, termination provisions, and other provisions contained in this Agreement and shall not exceed the scope of the license granted to Licensee hereunder. Promptly after execution of any sublicense agreement, Licensee shall give written notice to Scripps of the grant of such sublicense and details of the following material terms: (i) the name of the sublicensee, (ii) the duration of the sublicense, (iii) the Scripps Patent Rights and Scripps Technology that are the subject of the sublicense, and (iv) the commercialization obligations imposed upon the sublicensee.

2.7 Aggregate Royalties. In the event that a percentage of sublicense income or royalties are paid by the Licensee, an Affiliate or a sublicensee to an unaffiliated third party or to Scripps under a separate agreement in respect of a Licensed Product ("Additional Royalties") for which royalties are also due to Scripps pursuant to this Agreement, then the following provisions shall apply (either separately or jointly, as applicable):

(a) if the Licensed Product is or was claimed in whole or in part, in one or more of the Core Patent Rights and the Additional Royalties are due pursuant to a license agreement between Scripps and Licensee that is executed pursuant to that certain Research Funding and Option Agreement of even date herewith between Scripps and Licensee (such licenses are collectively referred to herein as "Other Research Licenses"):

5

(i) until the expiration of the last to expire of the Core Patent rights, the royalties under this Agreement shall be reduced such that the aggregate royalties due under this Agreement and the Other Research Licenses do not exceed Two and One-Half percent (2.5 %) of Net Sales of the Licensed Product;

(ii) after the expiration of the last to expire of the Core Patent Rights, the royalties under this Agreement shall be increased such that the aggregate royalties due under this Agreement and the Other Research Licenses do not exceed Seven percent (7%) of Net Sales of the Licensed Product.

(b) if the Licensed Product is or was claimed in whole or in part in one or more of the Core Patent Rights and the Additional Royalties are due under any license with a third party or any other license agreement between Licensee and Scripps, or if the Licensed Product is or was not claimed in any of the Core Patent Rights, then the royalties under this Agreement shall be reduced by the amount of the payments due to the third party or Scripps under such license agreements, subject to a maximum reduction of fifty percent (50%) of the royalties due hereunder.

2.8 Duration of Royalty Obligations. The royalty obligations of Licensee as to each Licensed Product shall terminate on a country-by-country basis concurrently with the expiration of the last to expire of Scripps Patent Rights utilized by or in such Licensed Product in each such country or, with respect to Licensed Products not utilizing any Scripps Patent Rights, ten (10) years after the date of first commercial sale of such Licensed Product in such country.

2.9 Reports. Licensee shall furnish to Scripps at the same time as each royalty payment is made by Licensee, a detailed written report of Net Sales of the Licensed Products and the royalty due and payable thereon, including a description of any offsets or credits deducted therefrom, on a product-by-product and country-by-country basis, for the calendar quarter upon which the royalty payment is based.

2.10 Records. Licensee shall keep, and cause its Affiliates and sublicensees to keep, full, complete and proper records and accounts of all sales of Licensed Products in sufficient detail to enable the royalties payable on Net Sales of each Licensed Product to be determined. Scripps shall have the right to appoint an independent certified public accounting firm approved by Licensee, which approval shall not be unreasonably withheld, to audit the records of Licensee, its Affiliates and sublicensees as necessary to verify the royalties payable pursuant to this Agreement. Licensee, its Affiliates and sublicensees shall pay to Scripps an amount equal to any additional royalties to which Scripps is entitled as disclosed by the audit, plus interest thereon at the rate of one and one-half percent (1.5%) per month. Such audit shall be at Scripps' expense; provided, however, that if the audit discloses that Scripps was underpaid royalties with respect to any Licensed Product by at least five percent (5%) for any calendar quarter, then Licensee, its Affiliates or sublicensee, as the case

6

may be shall reimburse Scripps for any such audit costs. Scripps may exercise its right of audit as to each of Licensee, its Affiliates or sublicensees no more frequently than once in any calendar year. The accounting firm shall disclose to Scripps only information relating to the accuracy of the royalty payments. Licensee, its Affiliates and sublicensees shall preserve and maintain all such records required for audit for a period of three (3) years after the calendar quarter to which the record applies.

2.11 Foreign Sales. The remittance of royalties payable on sales outside the United States shall be payable to Scripps in United States Dollar equivalents at the official rate of exchange of the currency of the country from which the royalties are payable, as quoted in the Wall Street Journal for the last business day of the calendar quarter in which the royalties are payable. If the transfer of or the conversion into the United States Dollar equivalents of any such remittance in any such instance is not lawful or possible, the payment of such part of the royalties as is necessary shall be made by the deposit thereof, in the currency of the county where the sale was made on which the royalty was based to the credit and account of Scripps or its nominee in any commercial bank or trust company of Scripps' choice located in that country, prompt written notice of which shall be given by Licensee to Scripps.

Any such tax actually paid on Scripps' behalf shall be deducted from royalty payments due Scripps.

3. Patent Matters.

3.1 Patent Prosecution and Maintenance. From and after the date of this Agreement, the provisions of this Section 3 shall control the prosecution and maintenance of any patent included within Scripps Patent Rights. Subject to the requirements, limitations and conditions set forth in this Agreement, Scripps shall direct and control (i) the preparation, filing and prosecution of the United States and foreign patent applications within Scripps Patent Rights (including any interferences and foreign oppositions) and (ii) maintain the patents issuing therefrom. Scripps shall select the patent attorney, subject to Licensee's written approval, which approval shall not be unreasonably withheld. Both parties hereto agree that Scripps may, at its sole discretion, utilize Scripps' Office of Patent Counsel in lieu of outside counsel for patent prosecution and maintenance described herein, and the fees and expenses incurred by Scripps with respect to work done by such Office of Patent Counsel shall be paid as set forth below. Licensee shall have will rights of consultation with the patent attorney so selected on all matters relating to Scripps Patent Rights.

Licensee shall pay for all expenses incurred by Scripps pursuant to Section 3.1 hereof. In addition, Licensee agrees to reimburse Scripps for all patent costs and expenses paid or incurred by Scripps to date in connection with Scripps Patent Rights licensed hereunder.

No such notice shall have any effect on Licensee's obligations to pay expenses incurred up to the effective date of such election.

3.4 Ownership. The patent applications filed and the patents obtained by Scripps pursuant to Section 3.1 hereof shall be owned solely by Scripps, assigned to Scripps and deemed a part of Scripps Patent Rights.

3.5 Scripps Right to Pursue Patent. If at any time during the term of this Agreement, Licensee's rights with respect to Scripps Patent Rights are terminated, Scripps shall have the right to take whatever action Scripps deems appropriate to obtain or maintain the corresponding patent protection at its own expense. If Scripps pursues patents under this Section 3.5, Licensee agrees to cooperate fully, including by providing, at no charge to Scripps, all appropriate technical data and executing all necessary legal documents.

3.6 Licensee's Right to Pursue Patent. If subsequent to filing a patent application on an invention within the Scripps Patent Rights, Scripps elects not to direct and control the prosecution or maintenance of such patent application or ensuing patent Scripps shall give Licensee notice thereof within a reasonable period prior to allowing such patent application or patent to lapse or become abandoned or unenforceable and Licensee may direct and control prosecution or maintenance of such patent application or patent at its expense and its exclusive benefit. If subsequent to filing of a United States patent application,

8

Scripps chooses not to file in foreign countries, Scripps shall inform Licensee within six (6) months of the United States filing date and shall permit Licensee to effect such foreign filings not made by Scripps at Licensee's sole expense.

3.7 Infringement Actions.

3.7.1 Prosecution of Infringements. Scripps and Licensee shall promptly notify the other in writing if any infringement of the Scripps Patent Rights by a third party is discovered or comes to its attention. Provided Licensee shall have supplied Scripps with reasonable evidence of infringement of Scripps Patent Rights by a third party, Licensee shall have the right, at Licensee's sole expense to bring suit against the infringer for infringement of the Scripps Patent Rights. In the event that Licensee has not caused such infringement to terminate (for whatever cause) or initiated legal proceedings against the infringer within three (3) months following receipt or giving of notice pursuant to this Section 3.7, Scripps shall have the right (but not the obligation), at Scripps's sole expense, to bring suit against the infringer for infringement of the Scripps Patent Rights.

3.7.2 Reasonable Assistance. In the event either party hereto shall initiate or carry on legal proceedings to enforce the Scripps Patent Rights against an alleged infringer, as provided herein, the other party hereto shall render reasonable assistance to and cooperate with the party initiating or carrying on such proceedings.

3.7.3 Control. In the event that either party shall institute suit or other legal proceedings to enforce the Scripps Patent Rights, it shall have sole control of such suit and the other party shall be entitled to be represented in any such suit by counsel of its choosing, at its sole expense. Licensee shall not discontinue or settle any such proceedings brought by it without obtaining the concurrence of Scripps (which concurrence shall not be unreasonably withheld) and giving Scripps a timely opportunity to continue such proceedings in its own name, under its sole control, and at this sole expense. In the event Scripps does not concur in such settlement, it must continue such proceeding in its own name, under its sole control and expense within three (3) months of being given notice by Licensee of its desire to settle or Licensee shall be entitled to settle without Scripps's concurrence.

3.7.4 Allocation of Recovery. All damages, settlements and awards made or obtained in connection with any suit or other legal proceeding under this
Section 3.7 shall be shared among the parties as follows:

(a) The party initiating the suit shall first be reimbursed for all costs and expenses of such suit or legal proceeding; in the event that the suit or other legal proceeding is initiated by Licensee but is later assumed, under
Section 3.7.3, by Scripps, Licensee shall first be reimbursed its costs and expenses and then Scripps shall be reimbursed its costs and expenses of such proceeding.

9

(b) If the Licensee initiated the suit and prosecuted it to its conclusion, Licensee shall be entitled to retain the balance of any damages, settlements and awards, less the royalty on such amounts due Scripps in accordance with Article 2.

(c) In all other circumstances other than that described in Section 3.7.4(b) above, Scripps and Licensee shall divide the balance of any damages, settlements and awards 60% to Scripps and 40% to Licensee.

4. Obligations Related to Commercialization.

4.1 Commercial Development Obligation. In order to maintain the license granted hereunder in force, Licensee shall use reasonable efforts and due diligence to develop Scripps Technology and Scripps Patent Rights which are licensed hereunder into commercially viable Licensed Products, and thereafter to produce and sell reasonable quantities of Licensed Products. Licensee shall keep Scripps generally informed as to Licensee's progress in such development, production and sale, including its efforts, if any and only to the extent it may do so without breaching the terms of any confidentiality agreement, to sublicense Scripps Technology and Scripps Patent Rights. Licensee shall deliver to Scripps a semi-annual written report and such other reports as Scripps may reasonably request. The parties hereto acknowledge and agree that achievement of the milestones described in Exhibit C attached hereto on or before the dates set forth therein shall be evidence of compliance by Licensee with its commercial development obligations hereunder for the time periods specified in Exhibit C. In the event Scripps has a reasonable basis to believe that Licensee is not using reasonable efforts and due diligence as required hereunder, upon notice by Scripps to Licensee which specifies the basis for such belief, Scripps and Licensee shall negotiate in good faith to attempt to mutually resolve the issue. In the event Scripps and Licensee cannot agree upon any matter related to Licensee's commercial development obligations, the parties agree to utilize arbitration pursuant to Section 10.2 hereof in order to resolve the matter. If the arbitrator determines that Licensee has not complied with its obligations hereunder, and such default is not fully cured within sixty (60) days after the arbitrator's decision, Scripps may terminate Licensee's rights under this Agreement.

4.2 Governmental Approvals and Marketing of Licensed Products. Licensee shall be responsible for obtaining all necessary governmental approvals for the development, production, distribution, sale and use of any Licensed Product, at Licensee's expense, including, without limitation, any safety studies. Licensee shall have sole responsibility for any warning labels, packaging and instructions as to the use of Licensed Products and for the quality control for any Licensed Product.

4.3 Indemnity. Licensee hereby agrees to indemnify, defend and hold harmless Scripps and any parent, subsidiary or other affiliated entity of Scripps and their trustees, officers, employees, scientists and agents from and against any liability or expense arising from any product liability claim asserted by any party as to any Licensed Product or

10

any claims arising from the use of any Scripps Patent Rights or Scripps Technology pursuant to this Agreement. Such indemnity and defense obligation shall apply to any product liability or other claims, including without limitation, personal injury, death or property damage, made by employees, subcontractors, sublicensees, or agents of Licensee, as well as any member of the general public. Licensee shall use its best efforts to have Scripps and, if requested in writing by Scripps, any parent, subsidiary or other affiliated entity of Scripps and their trustees, officers, employees, scientists and agents named as additional insured parties on any product liability insurance policies maintained by Licensee its Affiliates and sublicensees applicable to Licensed Products.

4.4 Patent Marking. To the extent required by applicable law, Licensee shall mark all Licensed Products or their containers in accordance with the applicable patent marking laws.

4.5 No Use of Name. The use of the name "The Scripps Research Institute", "Scripps", or any variation thereof in connection with the advertising or sale of Licensed Products is expressly prohibited.

4.6 U.S. Manufacture. To the extent required by applicable United States laws, if at all, Licensee agrees that Licensed Products will be manufactured in the United States, or its territories, subject to such waivers as may be required, or obtained, if at all, from the United States Department of Health and Human Services, or its designee.

4.7 Foreign Registration. Licensee agrees to register this Agreement with any foreign governmental agency which requires such registration, and Licensee shall pay all costs and legal fees in connection therewith.

10. General Provisions.

10.1 Independent Contractors. The relationship between Scripps and Licensee is that of independent contractors. Scripps and Licensee are not joint venturers, partners, principal and agent, master and servant, employer or employee, and have no other relationship other than independent contracting parties. Scripps and Licensee shall have no power to bind or obligate each other in any manner, other than as is expressly set forth in this Agreement.

10.2 Arbitration. Any controversy or claim arising out of or relating to this Agreement, or the breach thereof, shall be settled by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association ("AAA"), and the procedures set forth below. In the event of any inconsistency between the Rules of AAA and the procedures set forth below, the procedures set forth below shall control. Judgment upon the award rendered by the arbitrators may be enforced in any court having jurisdiction thereof.

10.2.1 Location. The location of the arbitration shall be in the City of Philadelphia.

10.2.2 Selection of Arbitrators. The arbitration shall be conducted by a panel of three neutral arbitrators who are independent and disinterested with respect to the parties, this Agreement, and the outcome of the arbitration. Each party shall appoint one neutral arbitrator, and these two arbitrators so selected by the parties shall then select the third arbitrator. If one party has given written notice to the other party as to the identity of the arbitrator appointed by the party, and the party thereafter makes a written demand on the other party to appoint its designated arbitrator within the next ten days, and the other party fails to appoint its designated arbitrator within ten days after receiving said written demand, then the arbitrator who has already been designated shall appoint the other two arbitrators.

10.2.3 Discovery. Unless the parties mutually agree in writing to some additional and specific pre-hearing discovery, the only pre-hearing discovery shall be (a) reasonably limited production of relevant and non-privileged documents, and (b) the identification of witnesses to be called at the hearing, which identification shall give the witness's name, general qualifications and position, and a brief statement as to the general scope of the testimony to be given by the witness. The arbitrators shall decide any disputes

15

and shall control the process concerning these pre-hearing discovery matters. Pursuant to the Rules of AAA, the parties may subpoena witnesses and documents for presentation at the hearing.

10.2.4 Case Management. Prompt resolution of any dispute is important to both parties; and the parties agree that the arbitration of any dispute shall be conducted expeditiously. The arbitrators are instructed and directed to assume case management initiative and control over the arbitration process (including scheduling of events, pre-hearing discovery and activities, and the conduct of the hearing), in order to complete the arbitration as expeditiously as is reasonably practical for obtaining a just resolution of the dispute.

10.2.5 Remedies. The arbitrators may grant any legal or equitable remedy or relief that the arbitrators deem just and equitable, to the same extent that remedies or relief could be granted by a state or federal court, provided however, that no punitive damages may be awarded. No court action may be maintained seeking punitive damages. The decision of any two of the three arbitrators appointed shall be binding upon the parties.

10.2.6 Expenses. The expenses of the arbitration, including the arbitrators' fees, expert witness fees, and attorney's fees, may be awarded to the prevailing party, in the discretion of the arbitrators, or may be apportioned between the parties in any manner deemed appropriate by the arbitrators. Unless and until the arbitrators decide that one party is to pay for all (or a share) of such expenses, both parties shall share equally in the payment of the arbitrators' fees as and when billed by the arbitrators.

10.2.7 Confidentiality. Except as set forth below, the parties shall keep confidential the fact of the arbitration, the dispute being arbitrated, and the decision of the arbitrators. Notwithstanding the foregoing, the parties may disclose information about the arbitration to persons who have a need to know, such as directors, trustees, management employees, witnesses, experts, investors, attorneys, lenders, insurers, and others who may be directly affected. Additionally, if a party has stock which is publicly traded, the party may make such disclosures as are required by applicable securities laws. Further, if a party is expressly asked by a third party about the dispute or the arbitration, the party may disclose and acknowledge in general and limited terms that there is a dispute with the other party which is being (or has been) arbitrated. Once the arbitration award has become final, if the arbitration award is not promptly satisfied, then these confidentiality, provisions shall no longer be applicable.

10.3 Entire Agreement: Modification. This Agreement sets forth the entire agreement and understanding between the parties as to the subject matter hereof. There shall be no amendments or modifications to this Agreement, except by a written document which is signed by both parties.

16

10.4 California Law. This Agreement shall be construed and enforced in accordance with the laws of the State of California.

10.5 Headings. The headings for each article and section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular article or section.

10.6 Severability. Should any one or more of the provisions of this Agreement be held invalid or unenforceable by a count of competent jurisdiction, it shall be considered severed from this Agreement and shall not serve to invalidate the remaining provisions thereof. The parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by them when entering this Agreement may be realized.

10.7 No Waiver. Any delay in enforcing a party's rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such party's rights to the future enforcement of its rights under this Agreement, excepting only as to an express written and signed waiver as to a particular matter for a particular period of time.

10.8 Name. Whenever there has been an assignment or a sublicense by Licensee as permitted by this Agreement, the term "Licensee" as used in this Agreement shall also include and refer to, if appropriate, such assignee or sublicensee.

10.9 Attorneys' Fees. In the event of a dispute between the parties hereto or in the event of any default hereunder, the party prevailing in the resolution of any such dispute or default shall be entitled to recover its reasonable attorneys' fees and other costs incurred in connection with resolving such dispute or default.
